This is a partial character sheet for Kamen Rider Zi-O. Visit here for the main character index. Subjective trope and audience reactions should go on the YMMV page.
- Time Jackers: "As of today, you are Kamen Rider (name of original Rider)."
Twisted versions of the Kamen Riders, these "Another Riders" are humans that use the power of an AnotherWatch infused with the power of a specific Rider to transform. They act as the Monster of the Week for this series, and are part of the Time Jackers' plan to rewrite time, though some do have their own agendas too.

Another Riders in General
- Artificial Zombie: The majority of Another Riders have a decayed, "patchwork" aesthetic to reinforce how alien they are compared to the genuine articles, to varying degrees. The exception is Another AgitΩ, which only plays the trope out in comparison to the main Rider; being visually indistinct from the tertiary Rider of the same name.
- Clothes Make the Superman: At the end of the day, no matter how horrifying the Another Riders and their transformations are, they're still just suits that the contract users wear to fight the heroes.
- Composite Character: All Past Another Riders' forms seem to draw aspects from their bases' more powerful forms, as well as appear similar to or display abilities/quirks from their monster contemporaries:
- Another Build: Has a mix of RabbitTank Hazard's and RabbitTank Sparkling's design aesthetics, and his body is covered in scrap metal just like the Smash. His consumption of Smash Bottles and him going berserk are based on specifically early victims of Smash experimentation.
- Another Ex-Aid: His wires resembles Hyper Muteki's "hair," with his appearance being based on a twisted version of Mighty, the main character from Mighty Action X, fitting with the Bugsters being video game bosses come to life, and of course, spreading the Bugster Virus with a touch.
- Another Ghost: Has Toucon Damashii's Persona design, and performs soul extraction as his modus operandi, which alluded to Knife Ganma and Katchu Ganma. His chest has a large eye similar to that of the Ganma's buckles along with eyes and horns similar to that of the Ganma Superiors, and is created by using Makimura's lifeless body, much like how Ganma gain their forms by possessing inanimate objects.
- Another Drive: The shoulder tire of Type Tridoron with the cobbled aesthetics of Super Deadheat. His grey face and twisted armor resembles that of the Roidmudes, as well as Proto-Zero’s face with Mashin Chaser’s armor. His twisted belt meanwhile resembles to that of Mach Driver Honoh instead of Drive Driver.
- Another Gaim: Kachidoki Arms' armor design and weapon type, which is a zanbatō, just like the Overlord Roshuo uses. His appearance, which has tree roots growing out of him, brings to mind the Helheim Forest and the vines resulting from humans transformed into Inves with the power to be able to create Cracks into an artificial Helheim much like the Overlords.
- Another Wizard: The coat design of Flame Dragon, while the short shoulder mantle is reminiscent of the White Wizard/Kamen Rider Wiseman suit. His host, Hayase becomes rampant after learning of his crush's engagement; The Phantoms, Kamen Rider Wizard's adversaries, are born from Gates falling into despair and the cracks in his faceplate bring to mind said Gates and when they become Phantoms.
- Another Fourze: Possesses Cosmic States' helmet design and Module Access, and retains the Photon Blood-like trails of orange and red from Another Faiz all along his body, which also alludes to the trails on a Zodiart's body. He molts into Another Faiz in the same way as Zodiarts evolves into Horoscopes.
- Another OOO: Super Tatoba Combo's coloring, and has a scarf based off eagle wings, like Putotyra Combo has a cape-like formation based off a pterodactyl's wings. He also has a hybridization of three animals, based on the three Greeeds of Ankh, Kazari and Uva, and bleeds Cell Medals upon receiving damage like them.
- Another Double: The bird-like design of the belt from CycloneJokerXtreme's Xtreme Memory, and the Joker half's spikes from FangJoker, and his right side's coloration and arm closely resembling the Nazca Dopant, a member of Double's antagonists, a secret Gaia Memory-distributing syndicate called Museum.
- Another Decade: Decade Complete Form's headpiece and leg armor with the eye design of Decade Violent Emotion. There is also a mish-mash of past Another Rider themes, much like how Tsukasa fought new version of past monsters in his series, as well as taking inspiration from Chinomanako’s Ayakashi Rakaider form from the Shinkenger crossover arc from his home series, and his identity is Swartz, an evil ruler with powers over space and time like Tsukasa himself.
- Another Diend: Summoning similar to Diend Complete Form with Chinomanako Diend’s head and armor along with Dark Decade’s driver design.
- Another Kiva: A mix of Kiva Emperor’s cape with the armor of Dark Kiva, and the ability to use all 3 Arm Monsters weapons like DoGaBaKi form, with the stained glass skin of the Fangire, and a roaring face resembling the Bat Fangire Reborn. Her twisted belt meanwhile, resembles the Legendorga King Kamen Rider Arc's Arc Kivat belt.
- Another Den-O: A mix of Sword Form with a few elements of Wing Form, such as his Mesoamerican-style belt buckle and arms, with the train track designs from Den-O Climax Form and New Den-O's Strike Form while also take cues from its Imagin user, Momotaros, as well as a western devil.
- Another Kabuto: Hyper Kabuto’s shoulder pads, thigh armor, and horn, with insect carapace for armor, bones formed through his body, and a head with skeletal hands covering his face similar to the Salis and Native Worms. His "belt buckle" looks like the larva of a beetle, going along with the Zecter's insect motif. His shoulder armor also makes him similar to the Godspeed Love villain, Kamen Rider Caucasus.
- Another Hibiki: Golden armor and horns of Armed Form with barbaric and animalistic features like the Makamou Parents, such as a wild black mane, demon mask, fanged face, and exposed toes, as well as design elements from S.I.C. Kabuki.
- Another Blade: Heavy armor like King Form, and a twisted sword appearing like a mix between the King Rouzer and the (Jack) Blay Rouzer. Her design of nailed metal spikes and plates as armor on leather also brings to mind the likes the Undead, with her knight motif specifically resembling the Category Ace Beetle Undead and Category King Caucasus Undead.
- Another Faiz: The Rider Kick-like attack of Blaster form's variant of the Crimson Smash and possesses the grey skin of the Orphnochs inherited from Another Fourze with a rib cage and shark-like features.
- Another Ryuga and Ryuki: Ryuga and Ryuki's Survive Form head and armor and also resembles the humanoid Mirror Monsters with their animalistic dragon armor and Ryuga's weapons being naturally part of them also brings to mind the Contract Monsters, whose body parts made up the weapons summoned by their users.
- Another AgitΩ: The design aesthetics are a mix similar to Lords and the original Another Agito, complete with Scarf Of Ass Kicking and unlike most Another Riders retaining the bug eye lenses. His chest armor design and forearm blades resembles Agito's Burning Form, while his ability to use Another Rider equivalent of Agito's weapons brings Trinty Form to mind. They are actually an inverse to the Lords, instead of seeking out people who had seeds of Agito and killing them due to it being taboo, Another AgitΩs bite them to turn them into Another AgitΩs themselves, spreading the power of Agito like a virus.
- Another Kuuga: A potential force of destruction like Kuuga's Ultimate Form, which the latter turns into, and his appearance has animalistic features like Gurongi, as well as their golden accessories. His use of insect wings to fly is also an allusion to the original Kuuga's support vehicle, Gouram.
- Another Ultimate Kuuga: Takes design cues from N-Daguva-Zeba, the strongest Gurongi, who is also a counterpart of the form. The allusions to the original Kuuga's support vehicle, Gouram, become more apparent due to being dyed black and having a longer pair of horns.
- Another Zi-O: Gains Zi-O II's Combat Clairvoyance, but also has Another Rider elements that are bolstered by not only being one himself, but being able to take the forms of any other Another Riders that have already been defeated. His faceplate, which is a skinned human face and ability to turn other humans into Another Riders also brings to mind the series main antagonists, The Time Jackers.
- Another Zi-O II: A mix of Zi-O II and Oma Zi-O's armor designs with Grand Zi-O's rider summoning and time reversal abilities.
- Another Zero-One: Design aspects similar to the upper body of Shining Hopper’s shoulder wings and Shining Assault Hopper Form along with having the Pest Controller ability and silver in the wings and shoulder armor of MetalCluster Hopper, with a similar face to the skinless HumaGears, seen before they’re turned into Magia. His twisted version of the Zero-One Driver also resembles the Ark.
- Another 1: An armored body like Power Up while being originally designated as a Shocker Kaijin, making them similar to the Action Commanders from the
35th Super Sentai Kaizoku Sentai Gokaiger as some of them had relations to Villains and Monsters from Gokaigers' predecessors. Its design is also similar to Kamen Rider Core's Bike State.
- Comes Great Insanity: No matter what sort of person they were before, receiving the power of an Another Rider will transform the subject into a destructive, evil creature obsessed with a twisted version of their original desires. The exact time period varies from person to person, but the change is inevitable.
- The Corruption: The AnotherWatches seem to twist the minds of the people using them, causing them to do horrible things that they never would've done otherwise with Another Fourze/Faiz's spree killings being a good example. Just using the Zi-O II AnotherWatch to revive Tsukasa caused it to turn Kaito into Another Zi-O II and try to kill Tsukasa again.
- Curb-Stomp Battle: If an Another Rider happens to face the original Rider they're based on, it usually ends in a curb stomp in the original Rider's favor. The only exception is Another Zi-O who can only tie with Zi-O II.
- De-power: Another Faiz, the oldest Another Rider thus far, had his powers start to fade after several years of usage, requiring him to accept a second watch to get them back. It's not clear if it happens to all Another Riders eventually, but if it does, it provides a pretty clear method by which the Time Jackers can control their creations.
- Evil Makes You Monstrous: They are hideous travesties of the Riders they are based on and turn any user to evil. Some are so far gone that they barely resemble the original anymore.
- Evil Knockoff: Naturally. Being amalgams of their Rider and the monsters of the Rider’s series, they all look like twisted, monster-ized versions of famous Kamen Riders with Spikes of Villainy, Scary Teeth, and similar design changes, with a recurring theme is that they also seem to be the opposite to the Rider whose powers they're granted.
- Most notably, unlike the compound eyes that most Kamen Rider designs use, Another Riders have a single pair of monstrous eyes underneath a colored visor.
- Sento is a kind, if insufferable genius. His Another counterpart is an athlete, and far less noble and intelligent than he is. While Sento gained his Fullbottles from purifying people and saving them, Another Build turns people into his bottles.
- Another Ex-Aid isn't a gamer, but rather a concerned father. Like Emu he has noble reasons to do what he's doing, but unlike our resident pediatrician he's willing to take away the smiles and good health of others to save one life in particular. And of course, rather than curing illnesses, he's spreading one around.
- Rather than being an undead-like Orphnoch himself, Another Faiz actually revived another person from death, while maintaining their life by feeding it off from other people much like a Fangire instead. Another Fourze-wise, he is a loner who actually mirrors Ryusei Sakuta/Kamen Rider Meteor instead, with a similar name, backstory and objective.
- Another Wizard's powers are fueled by despair and hatred instead of hope, becoming more powerful once he had passed the Despair Event Horizon.
- Another OOO may look like a Greeed but actually has far more in common with the original Kamen Rider OOO, a greedy evil king, personality-wise than Eiji did.
- Another Gaim is a self-absorbed tyrant who is obsessed with being the best, taking all of the worst parts of Kouta's rival and opposite Kaito, along with his friend and other opposite Mitsuzane, and exaggerating them with none of the positives.
- Another Ghost, rather than keeping others alive while their own flames of life slowly burns out, actively goes and steals the lives of "troublemakers" in order to fuel their fire, keeping Another Ghost right on the line between life and death.
- Another Shinobi, unlike his noble future self, takes his "justice" to the extreme, contrasting the more calculated moves Rentaro performs as Shinobi.
- Quiz, despite his air of smugness, still has a form of moral codes to follow, and his motives are noble. Another Quiz, his father, however does anything to achieve some sort of recognition, a selfish motive.
- Another Ryuga pulls triple duty as it based off a rider who was an Evil Knockoff of another rider who behind the mask is an Evil Knockoff of the main character of Kamen Rider Ryuki. Function-wise, he is the reverse in that he needs to transform to access the real world, unlike a standard Rider who transforms to access the Mirror World.
- Where Rento Makina/Kikai is a strong-hearted mechanical defender of humanity, Another Kikai is a piece of Organic Technology based on wood that is as mindless as they come. Meanwhile, Heure going berserk from the powers of Another Kikai parasite, somewhat parallels to when Rento Makina gets reprogrammed from his satellite, leaving him out of control as well. Both were rescued by inputing the passcode "Will Be The —-"
- Another Zi-O is everything Sougo isn't. He is vicious, self-serving, uncompromising and Sougo's determination to reach his goal of being king is given a twisted mirror in Hiryu's single minded obsession with killing Sougo. Another Zi-O acts like the worst parts of early series Sougo and early series Geiz combined. His return in the Another Zi-O II arc gives him traits of Oma Zi-O where he rules the world as the Overlord, fights the resistance that includes Geiz and Tsukuyomi and has Woz as his hearld but unlike Oma Zi-O who thinks he's saved the world through his actions, Hiryu is doing this just to spite Sougo.
- Another Blade is someone unwillingly transformed into an abomination for the sake of threatening the world through exposure to a loved one whose actions would endanger the world; the reverse of the original Blade, who willingly gave up his humanity to save said world. The original Blade also spent his series escaping his Ineffectual Loner status and learning to reach out to others, whereas Another Blade's Anotherwatch transforms them into a single-minded angry loner that dismisses others.
- Another Ryuki's original counterpart is a selfless protector who wants to preserve life and minimize fighting. Another Ryuki meanwhile is a cold, ruthless creature who is perfectly fine with harvesting innocent lives to save the person he loves. If anything, he parallels Ryuki's main villain Shiro Kanzaki more. Even more so, as wheras Shinji is Shiro's Spanner in the Works, Another Ryuki is Shiro's puppet.
- Another AgitΩ is actually a knockoff enforced by the rules of Agito's home series. As there can only be one Agito at a time, anything that would become an Agito instead becomes something else like Gills or the original Another Agito. In this sense the Another AgitΩs fall into this ironclad rule. Individual-wise, the original was an amnesiac who eventually merged his old and new identity while the Another Riders completely lost their identity.
- Another Hibiki was a former disciple who was forced to take the easy way to become an Oni and was disillusioned after learning the truth about his teacher. The original always trained his best in order to remain strong and had an excellent work ethic.
- Another Kiva was imprisoned for years thus is strong-willed and determined to become Queen of the World to "right the world", the opposite of the original Kiva who willingly stayed in his home and was an Extreme Doormat despite his destiny as King of the Fangire. If anything, her personality is more or less a genderbent Fangire King.
- While a jerk, Tendou is ultimately a calm and collected man whose idealism lets him fight for justice and the future of humanity and Native Worms. Yaguruma on the other hand, after losing TheBee Zecter, became an angry nihilist who only fights after getting riled up. In Zi-O, Yaguruma fights to protect the Worm pretending to be Kageyama mirroring Tendou's motivation to protect Hiyori. But while Tendou fought to save Earth, Yaguruma willingly helps the Worm as he attempts to turn Earth into a living hell.
- The second Another Den-O who took the Anotherwatch does not approve of his sister's boyfriend because he felt that he was responsible for her death, in contrast to the original Den-O who looked up to the original Sakurai as an older brother figure and still respecting the younger, more immature version. They both worked with Imagin in unconventional ways but while Ryotaro had the Taros possess him to fight as Den-O, Takuya works with a single Mole Imagin that used the DenLiner to make copies of himself to act as an army.
- Another Drive is a relentless follower of Swartz who does not stop in her mission to capture Heure and is as emotionless as possible, while the original Drive is by far the laziest main Rider and makes a quip on just about everything. Her identity as Paradox Roidmude taking the form of Ora brings in mind how the original Drive and Mr. Belt working together while Roidmude 108 combined with her past self for more power.
- Another Decade is none other than Swartz himself, the main antagonist who wants to conquer time and space by first manipulating Sougo into becoming his proxy before deciding to become Another Decade so he can take over as the Demon King. The original Decade was also the main leader of an antagonistic organization but even when he regained his memories and became the Destroyer of Worlds, he still became the Big Good for many of the Kamen Rider crossovers.
- Aruto Hiden is a young, bumbling human who rightfully inherits the role of Hiden Intelligence's CEO and becomes the computer-themed Kamen Rider Zero-One. Though somewhat incompetent, he loves his employees, Humagear, and other humans equally. Will, on the other hand, is a Humagear who becomes the far more insectoid Another Zero-One to take the role of CEO by force, and uses his competence to declare war on humanity, including Hiden Intelligence's members.
- Daiki Kaito is a Manipulative Bastard and mostly operates to steal treasures from other worlds, while often flip-flopping with his alignment towards Tsukasa - as does Another Diend's user, White Woz, in a sense with Geiz. However, while Daiki tries to stay on the good side of the protagonists despite his shaky morals, White Woz has no intentions of truly doing so as Another Diend, and is only in it to Kill and Replace Geiz.
- Takeshi Kinashi is an Affectionate Parody of Takeshi Hongo, but still has a place in the collective memories of the Kamen Riders, and, as Over-Quartzer implies, was still a man who fought real villains. No Rider, on the other hand, is a "parody" bereft of any meaning or heroism, created as a crude-looking, hollow monster to stop Zi-O.
- Geiz and Tsukuyomi are members of La Résistance who traveled back to 2018 in the hopes of preventing Ohma Zi-O's rise. Another Geiz and Tsukuyomi are devotees of a new Ohma Zi-O, created so that Another Woz has a means to manipulate time for himself to ensure the Stable Time Loop maintaining his world remains.
- Woz is the sycophantic prophet of Ohma Zi-O who travels back to 2018 to ensure his rise, but eases into the new future created by Sougo as the plot develops and becomes a hero himself. Another Woz not only lacks the real Woz's Character Development, but is willing to break time in much the same way that Swartz did by forming time loops and creating more Another Riders.
- Forced into Evil: Many of the Another Riders were simply normal people who only became Another Riders in order to stop their or their loved one's untimely death. They just didn’t know that doing so meant becoming an insane monster driven to accomplish their goal at any cost. Those who don't accept the deal are quick to learn that the deal isn't actually a "deal" at all, as the Time Jackers don't take no for an answer. The only difference between an accepting host and a rejecting host is the fact that the resulting Another Rider won't have a mind of its own, and the resulting Another Rider is noticeably weaker if the host is unwilling.
- Glowing Eyes of Doom: When an Another Rider transforms, their "eyes" glow, the exceptions are the horns of Another Den-O, the face of Another Ghost, or whatever the lines on Another Hibiki's face are.
- Laser-Guided Amnesia: It's revealed in ep 25 that because of defeating the Another Riders at the year of their creation, the contract hosts have no memories of meeting the Riders due to the changed timeline. This is supported as Sougo tries to reintroduce himself to Hayase, but the latter has no idea who he is.
- Linear Warriors, Quadratic Wizards: Another Riders are the linear warriors to the quadratic wizards of the genuine articles. In exchange for not being able to use the more impressive abilities that the real Riders possess in their more advanced forms, Another Riders usually display the ability to use all of the combined abilities of the Rider's various first-quarter forms, or use abilities such as Fourze's Switches or Wizard's spells instantly without the real Rider's toy-swapping gimmickry. They also display no growth in power over time, unlike the real Riders: if anything, there's implications that Another Riders are at their strongest when they're first created. Averted with Another Zi-O, who managed to survive it's destruction and evolve into Another Zi-O II, who's powers are equal to Grand Zi-O and Another Decade who became so powerful that it took Sougo becoming Oma Zi-O to finally defeat him once and for all.
- MacGuffin Delivery Service: The Another Riders as a whole are eventually revealed to be this, as none of them ever really had a chance at replacing Zi-O as king. Their only purpose is to force him to steal the powers of the other Heisei Riders in order to defeat them, guiding him down the path to becoming Oma Zi-O. Another Decade is the only exception, being the tool by which Swartz plans to take the completed powers of Oma Zi-O for himself.
- Monstrosity Equals Weakness: In all but a few cases, the freakish Another Riders are shown to be significantly weaker than their uncorrupted counterparts. By the end of the series, only two of them (Another Zi-O II and Another Decade) come close to approximating the power of their namesake’s highest forms without some additional gimmick.
- Nightmare Face: All of them have this trait, being twisted monster versions of beloved heroes. They all have pretty nasty fanged mouths, and many of them have visible eyes as well. If the heroes are "Masked Riders", then these are Unmasked Riders.
- Another Blade gets this especially because of the fact that its face is rather normal except for one detail. Its eyes. Its bloodshot, almost human eyes.
- Non-Lethal K.O.: Like other Heisei era humans-turned-monsters (except those poor Inves) they are restored to their human form upon defeat...even if Gaim Armor just sliced them into pieces.
- Resurrective Immortality: Another Riders will simply come back to life if killed, appearing back as if the killing blow never happened. The only way to defeat them permanently is to use the power of the original Rider they're based on in the year that their Rider began. By midpoint of the series, the protagonists obtain forms that let them break the rules and permanently destroy Another Riders even without their assigned power set.
- Single-Issue Wonk: Justified, due to The Corruption effect of Anotherwatches. Most Another Riders develop a dogged, single-minded commitment to whatever they're working towards when transformed that's very difficult, if not impossible, to reason them out of.
- Another Build: Seeking out Best Matches from athletes due to pure instinct.
- Another Ex-Aid: Iida's obession of putting young men in comas for the sake of his dying son.
- Another Fourze/Faiz: Ryuichi's obsession of stalking and killing girls in order to keep Karin alive.
- Another Wizard: Hayase's obsession of using magic to be with Kaori, which becomes using said magic to kill her once he finds out she's getting married.
- Another OOO: Kuroto's obsession with ruling over all for the sake of his greed.
- Another Gaim: Asura's obsession with being the best, and ruling over Team Baron with an iron fist, due to being kicked out of Team Baron in the original timeline.
- Another Double: His loyalty for Tid.
- Another Den-O: Ataru's hatred of all Kamen Riders due to the Another Den-O Ridewatch itself.
- Another Kuuga: Tid's desire to be "the only Rider," so that he can erase the Kamen Riders from existence and rule, and later destroy the world, because he believes he should be the only one to smile.
- Another Ghost: Makimura's obsession of seeking out future "trouble makers" and stealing their souls to stop future incidents, due to being half-dead and brainwashed by Heure.
- Another Shinobi: Rentaro's obsession of meting out "justice" by attacking his friend's bullies, and then "becoming king" once that was done.
- Another Quiz: Tamotsu's obsession of stealing knowledge in order to change his fate of never proving anything, as well as saving his wife.
- Another Ryuga: Dark Shinji's obsession of seeking out revenge at former ORE Journal members due to being born from Shinji's resentment of ORE Journal closing down.
- Another Kikai: Lashing out and destroying everything, due to being a mindless monster born of a Time Paradox as a result of Kikai's creation.
- Another Zi-O: Hiryu's obsession of seeking revenge against Sougo, due to Hiryu blaming him and Tsukuyomi for his parents' death.
- Another Ryuki: Tatsuya's obsession of preventing Sara from dying by killing others, using their souls to keep her alive.
- Another Blade: Amane's obsession of finding Hajime, as well as ending the world thanks to White Woz.
- Another AgitΩ: Spreading the power of Another AgitΩ, due to the Time Jackers seeking out the original Agito.
- Another Hibiki: Tsutomu's wish to be an Oni, just like Hibiki, due to finding out that Kyosuke Kiriya was not actually Hibiki.
- Another Kiva: Yuko's wish to right the laws of the world by becoming the "Queen of the World", due to being unfairly locked up in prison for a murder she didn't commit (that she lied about and actually did).
- Another Kabuto: Yaguruma's obsession of being with his deceased partner Kageyama, to the point of willingly team up with a Worm taking his form, due to being the one responsible of killing the original one.
- Another Den-O II: Takuya's obsession of revenge against his sister's lover, due to blaming him for her death.
- Another Zi-O II: Hiryu's desire to make Sougo go through hell, because of his own inability to move on. When Kaito became the user, his spurned relationship towards Tsukasa are dialed to a degree instead.
- Another Drive: Paradox Roidmude's desire to be real by killing Heure and then Ora so she can be the "only" Ora around.
- Another Decade: Swartz's desire for absolute power, due to being turned down as ruler in his timeline in favor of his sister.
- Another Zero-One: Will's obsession of exterminating humanity due to believing that HumaGears are superior. Unlike most cases though, it didn't brainwash him. It just gave him the power to put into action what he was planning in the unaltered timeline.
- Another 1: Finis's desire for chaos and destruction of the Kamen Rider multiverse, due to wanting revenge on Sougo for killing Swartz, they were loyal to.
- Another Diend: White Woz's desire to be the Savior to ensure that his future will come to pass.
- Another Oma Zi-O: Hiryu's desire not only to defeat Sougo and get rid of Oma Zi-O, but to live in and/or rule something other than the Heisei Era and onward, which he now wishes he wasn't born in.
- King: King's desire to Take Over the World combined with Spade's desire to achieve the Time Jackers' goals without a Kamen Rider's powers.
- Shadow Archetype: From their aesthetic to motivations, each Another Rider serves as an dark, twisted reflection of the respective Rider whose history they have stolen. In many ways, each theme and ideology each Kamen Rider embodies can be considered Gone Horribly Right through the Another Riders' existence.
- Soul Power: Multiple Another Riders have shown the ability to absorb people and use their souls to get stronger.
- Takes One to Kill One: Another Riders are only able to be destroyed using the power of the Rider they're based on. Under normal circumstances, this means using a Ridewatch, because the Another Rider's creation erases the original Rider, but if the original Rider is immune to being erased, like Den-O, or the Another Rider is created in the present, then they can defeat their Another Rider counterpart personally. The Another Riders based on the future Riders can't be destroyed by those real Riders, however: only a Miridewatch will work. Zi-O II, Zi-O Trinity, and Woz GingaFinaly can also break the rules and destroy Another Riders without need for any particular watch.
- There Can Only Be One: Originally when an Another Rider was created by giving a watch to a person in the past, they existed by stealing the history of the Rider they're based on, creating a new timeline where the Rider and their villains never existed, making defeating them difficult. Only Zi-O or Geiz can defeat them for good once they obtain their respective Ridewatch. After the multiple paradoxes created by Kamen Rider Woz, Zi-O II, Geiz Revive and Zi-O Trinity, the Another Riders are now born in the present with the year 2019 replacing their counterparts original year on their markings. This means that the original Riders are now able to battle their evil counterparts and also means that if they transfer their powers to a Ridewatch they retain their original timelines. What this means for the riders whose timelines were erased remains to be seen.
- Took a Level in Badass: After Another Ex-Aid, the Time Jackers continually make defeating the next Another Rider (with the exception of Another Wizard and Another Ryuki) more complicated so they can finally defeat Sougo and Geiz:
- Sakuma was originally granted the powers of Faiz, but Swartz later gave him the Fourze powers as an experiment, requiring both forms to be simultaneously defeated in 2003 and 2011.
- Another OOO has a year plate that is mistakenly read as 2016, and drops a 2016 Genm Ridewatch, which throws Geiz off of OOO's real origin, and has a pre-existing god complex which made him fully cooperative with the Time Jackers.
- Another Gaim comes with an artificial Helheim where he imprisons dissidents, threatening innocent lives.
- Another Ghost is only alive because of his Watch; defeating him would also kill the human.
- Although shown only with Luna, Another Double is implied capable of accessing other forms of Kamen Rider Double rather than sticking to just a basic form like all general Another Riders.
- Even after being beaten by the Time Mazine enpowered by the same Rider, Another Kuuga's Watch survived its defeat, which in turn allowed Tid to absorb Shingo and becomes the Another Rider that resembled Kuuga's strongest form, Ultimate Kuuga.
- Another Shinobi is the first of the future Riders, safe in a timeline the protagonists can't access to create a Ridewatch from. Another Quiz is similar, but his unique change comes not from the Time Jackers, but White Woz.
- Another Ryuga is from a timeline that no longer exists, can travel through the Mirror World freely, and has the ability to perfectly reflect any attack that hits him, meaning defeating him could kill the attacker. Much like Another OOO, he is also in complete control of his power, but without Kuroto's insanity holding him back.
- Another Kikai, in addition to being another Future Rider, is not a watch but a Puppeteer Parasite, which can possess any organism should the one it's currently possessing be defeated.
- Another Zi-O can not only transform into other Another Riders to prevent his Another Zi-O watch from being destroyed, but is also the first Another Rider who willingly accepted it. This results in him being far more in control during combat. He also has Zi-O II's Combat Clairvoyance, nullifying Zi-O II's.
- Another Blade is the first Another Rider who didn't recieve the Anotherwatch from the year its rider aired and thus didn't take the place of the rider, and is actually an inversion, as she is weaker than Blade. At the same time she is also the one of the most dangerous Another Riders as she was used as bait to lure out Kenzaki and Hajime to restart the Undead Battle Fight, which will cause the End of the World due to both of them being Jokers. This gets worse when Amane absorbs both Kenzaki and Hajime's Joker powers, finally ending the battle royale with a Joker as the victor.
- Another AgitΩ is weak enough that any of the Riders on their own can defeat it. However, Another AgitΩ can multiply itself like a virus, meaning that not only can it overwhelm even the original Agito with sheer numbers, but if left unchecked, it could cause a Zombie Apocalypse of Another AgitΩs. He then claims the powers of Agito itself, turning him into Agito Ground Form.
- While Another Hibiki isn’t special power-wise, the fact that he is someone both Sougo and Kiriya knows complicates things and made them at odds with each other because of what both of them want to do with him.
- Another Kiva’s will is so strong that she is able to shrug the orders the Time Jackers usually give to each Another Riders and is such a skilled manipulator that she tricked Sougo into thinking that she’s someone in his past. In addition, unlike the other Another Riders who uses some sort of knockoff, she is able to use the genuine article of Kiva’s abilities (in this case, the use of the Arms Monsters).
- Another Kabuto is also Sou Yaguruma a.k.a. Kamen Rider KickHopper, allowing him to perform double duty as both Another Rider and an actual Kamen Rider. Turning into Another Kabuto while still in his Kamen Rider form somehow gives his Anotherwatch protection from being destroyed.
- The first Another Den-O (Ataru Hisanaga) loses to the Rider he is based on when each Taros take turns to beat him. Although lacking the Another Denliner, the new candidate (Takuya Endo) can fight against 3 of the very same Taros that curbstomped his predecessor and even compensate his lack of time train by stealing the actual Denliner itself.
- Another Zi-O II not only came back, but is the first Another Rider to receive a Super Mode. Not only can he summon Another Riders without hosts, but can locally rewind time just like Zi-O II to negate their destruction, making him more equal to Grand Zi-O.
- Another Drive can easily shapeshift into Ora, allowing her to sow discord towards the heroes and because she's a Roidmude, she can cause Heavy Acceleration. She also has her own version of the Tridoron to help her in combat.
- Another Decade is the Big Bad Swartz himself, which means that not only does he have Decade's already impressive powers, but also has his Time Master powers. He can also uses Decade's Dimension Walls to summon Dark Riders from alternate realities, stacking the deck even further.
- Because the timeline for Zero-One has temporarily changed, Another Zero-One has his own army of HumaGears hunting down humanity including alternate versions of Horobi and Jin, making it difficult to even reach him. Also, unlike many of the other host, Will was never brainwashed, having had his plan before the events of the movie even started.
- Due to a freak accident involving Another 1 absorbing Geiz's Time Mazine, they are able to evolve even further into a more powerful form, replacing their lower bike half with a grasshopper body.
- Transformation Horror: Every single one of them, some more than others. Each one of them becomes wrapped in bizarre, paint-like shadows. Once they've become completely enveloped in it, they burst out, with effects being based on the rider in question.
- Another Build: Nebula Gas.
- Another Ex-Aid: Pink pieces of data, usually used for when a game stage is generated.
- Another Fourze: The same blue "rocket smoke" and line effects as the original.
- Another Faiz: Black smoke that follows with red lines shining within it, opposed to 555 riders being enveloped in light as they transform.
- Another Wizard: Flames that quickly burn away, like Wizard's Flame Style.
- Another OOO: A bright light that glows through the body, a la La To Rata Combo.
- Another Gaim: Juice that looks rotting, opposed to Armored Riders' "fresh" juice.
- Another Double: While the host was never shown, the body was forming when it first appeared covered in a tornado with black dust.
- Another Den-O: Both the original and the second one have armor parts form around them first before the helmet covers their head, along with dark, red clouds and red lighting.
- Another Kuuga: A great dark aura of red and black, along with yellow lighting, before exploding in a pillar of fire, darkness, and lighting, just like when Kuuga defeated the Beetle Gurgoni and blew up in a pillar of fire.
- Another Ultimate Kuuga: A great dark aura of red and black, along with yellow lighting, before becoming a purple cloud that becomes Another Ulimate Kuuga.
- Another Ghost: Darkness followed by eerie orange light from his face, arms, legs, and eye in the chest.
- His later reappearance under another user has him summon four shadowy parka ghosts that engulf the user before continuing with the usual sequence.
- Another Shinobi: Purple cyclone, followed by purple lighting.
- Another Quiz: Red and blue mist, filled with question marks and exclamation points, signifying Quiz's correct and incorrect colors.
- Another Ryuga and Ryuki: Shimmers in grey and black, just like the original rider transformation.
- Another Kikai: Generates the face-hugging parasite first, which grows a cocoon of black vines around the host before bursting in a green light similar to Kikai's glow.
- Another Zi-O: Produces bony "watch straps" that revolve in a sphere around the user while generating the suit.
- Another Blade: A blue flaming card with Another Blade's mug appears in front of the user before sliding back, just like the Rouze Card Riders when they transform.
- Another AgitΩ: Emits white smog before being revealed to the public.
- Another Hibiki: Coat in purple flames before dissipated them referencing to Hibiki's default form transformation.
- Another Kiva: Produces a swarm of bats that surround her as the suit forms, the bats then disperse as she breaks out of a layer of stained glass to complete the transformation.
- Another Kabuto: Breaks outs of KickHopper a la CastOff in a aura of orange-red.
- Another Zi-O II: Produces golden, bony "watch straps" that revolve in a sphere around the user while generating the suit.
- Another Drive: Two red tires surrounding the body slam on each other with red exhaust fumes appearing after the transformation.
- Another Decade: The lines/cards that form Another Decade's face appears in mid-air while the suit generates, splitting into multiple silhouettesnote that fade away before the mid-air lines/cards slide into place on his head.
- Another Zero-One: A bright yellow double helix shaped energy wraps around the body with Tron Lines of Another Zero-One's body appearing before the body is formed.
- Another 1: Extensions of the shadow pops up and circles around the body while the host's size increases.
- Another Diend: Three silhouettes split away, a reverse of Diend's three silhouettes merging together.
Past Riders made in respective year
Another Build
Portrayed by: Taisei Mori (live)
An unnamed basketball player originally fated to suffer a Career-Ending Injury from a car accident in 2017. He was saved by Heure, on the condition of becoming Another Build.
- Area of Effect: Another Build's Swimmer/Archery Best Match causes the area around him to become liquid, but not melt, like when he is under the bridge, he could jump anywhere within it.
- Borrowed Catchphrase: He uses Sento's trademark "Best Match!", and at one point imitates his signature pose.
- Brainwashed and Crazy: Unlike the later Another Riders that followed, Another Build is more feral and animalistic, speaking in simplistic manner and seemingly unable to retain enough of a human will to be able to change between human and Rider forms. His entire motive for absorbing atheletes into his Full Bottles is even implied to be just his instincts forcing him to find Best Matches out of them.
- Cannibalism Superpower: He has the ability to absorb others into his "Full Bottles" before consuming them to gain their powers, a twisted take on Kamen Rider Build's own method of dealing with the Smash in his series. Apparently they have to be "Best Matches" for him to properly use them, but what criteria makes the sports a "Best Match" is unknown. For example: Karate and Tennis are not Best Matches but Swimmer and Archer are.
- Dumb Jock: Another Build is the exact opposite of the genius his namesake was, making him about as sharp as the basketballs he throws.
- Earn Your Happy Ending: Because of Heure, and later Sougo and Geiz's intervention, the boy whose supposed to receive a Career-Ending Injury gets to live a normal life as an athlete, as seen in 2019. At least until the Another Zi-O Arc.
- Energy Bow: Another Build's Swimmer/Archery Best Match gives him the ability to create this, allowing him to snipe his enemy from his hard-to-reach Area of Effect.
- Exotic Eye Designs: Lifting away the rabbit and tank covers from his eyes reveals that his “eyes” are actually a pair of cogs.
- Hulk Speak: When he meets Ryuga Banjo, he says "Me, Build. You, Cross-Z" while paraphasing Sento's "Best Match!" and his winning formula pose.
- I Know Madden Kombat: He is obsessed with sports, hunting down athletes to use their skills in combat for himself.
- In a Single Bound: As Another Build has the original features of Rabbit Fullbottle, his version of the Hop Springer also works similarly to the real Build's allowing him to make quick high jumps.
- Improbable Sports Skills: Another Build can summon basketballs from his hands, even going so far as to attempt a slam dunk on Zi-O. Given his previously being a basketball player, the sports skills themselves aren't improbable...but the method they're used in certainly is.
- Jerk Jock: Another Build's Fullbottle powers derive from athletes, his original self was a basketball player, and he terrorizes the innocent.
- No Name Given: His true name was never identified. Shirakura has explained this character was intentionally left unnamed as he was still set to appear in a future episode. However, that episode came and went without revealing his name.
- Power Copying: In a twisted version of Build gaining power by purifying Smash essence, Another Build can capture humans in Fullbottles and then gain powers based off of their skills. However, from what we saw, unlike Build, Another Build swallows the Fullbottles to access mentioned skills. For example, a captured swimmer lets him "swim" through solid surfaces as if they were water and a captured archer lets him create an Energy Bow.
- Starter Villain: As the first Another Rider in Zi-O, he has little to no characterization and is mostly there to introduce the concept of the series' monsters.
- Tank Goodness: As Another Build has the original features of the Tank Fullbottle, his version of Build's Tank Roller Shoe is fully functional, being able to use the tracks' movement to enhance the damage of his kicks.
Another Ex-Aid
Portrayed by: Takashi Kodama (live)
A civilian named Iida whose son Keisuke was sent to the hospital in 2016 due to a heart condition. He accepted Ora's offer to become Another Ex-Aid in order to save his son by inflicting other boys with a special strain of the Bugster Virus to find a heart donor.
- Big "SHUT UP!": His response to Sougo's attempt to talk him out of being Another Ex-Aid.Iida: Shut up, Just shut up already! While you're prattling on, my son is dying! He's running out of time!
- Dimensional Traveler: Another Ex-Aid can use the Game World as means of traveling into portable consoles.
- Earn Your Happy Ending: Thanks to Sougo telling Emu to tell Hiiro about Keisuke's condition while in 2016, Hiiro's is able to save him. As a result, both Keisuke and his father are seen happy together. At least, until the Another Zi-O Arc.
- Irrational Hatred: With the Another Ex-Aid Watch and the knowledge that Keisuke was destined to die, he's got little trust or patience for doctors. This is changed in the new timeline, where Keisuke was saved.
- Irony: Iida was first introduced in a scene where his son was being sent to a hospital due to illness. His cameo in the Another Zi-O arc has him being sent to the hospital after Hiryu attacked him.
- Konami Code: A "backdoor" exists within his game that allows people to access his game world should they enter a modified version of the Konami Code, hitting all the face buttons instead of B+A+Start
- In a Single Bound: Like the Rider whose powers it stole, Another Ex-Aid can jump great heights.
- Messy Hair: Unlike Ex-aid's "hair," his hair is more realistic, beings pink strings and gives of savage and wild look. It also draws aspects from Ex-aid's final form, his wires resembling Muteki Gamer's long hair.
- Mook Maker: Just like the Bugsters from Ex-aid, Ida can summon Bugster Viruses-like minions to attack his enemies.
- Plague Master: A specialized strain of Bugster Virus A that Another Ex-Aid uses to infect young boys who are potential heart donors to his son. It also severs as the source of his Mook Maker ability.
- Poor Communication Kills: Emu has been trying to contact him to get him to give up being an Another Rider and stay by Keisuke's side, but failed to convey that he means "to give him emotional support while we try to save him." As a result, Mr. Iida's addled mind thinks Emu's trying to tell him "be there for your son as he dies."
- Sanity Slippage: Using the corrupting powers of Another Ex-Aid to send young men into comas trying to find donors for his son's heart condition for two years has left Mr. Iida just a little bit unstable. As such, Sougo and Emu weren't able to talk him down.Iida: (after being told by Emu to be there for his son) What are you saying? You want me to sit around and wait for Keisuke to die?! If doctors like you won't save him, I'll do it myself. Stay out of my way.
- Shout-Out: His appearance bears a striking resemblance to Predator.
- Stealth Hi/Bye: He attacks people who play an "unbeatable" Genm Corp. game, appearing out of nowhere to do so.
- Terrain Sculpting: Thanks to his Another Kimewaza Slot Holder, Another Ex-Aid can affect the reality of the real world using Game Areas.
- Urban Legends: The game that cannot be cleared by anyone, a modified version of "Mighty Action X" which became known as an "unbeatable game" because anyone who tries to clear it gets attacked by Another Ex-Aid and left in a coma.
- Well-Intentioned Extremist: Iida is responsible for putting young men in comas to find a suitable candidate for his son's failing heart.
Another Fourze/Another Faiz
Portrayed by: Atomu Mizuishi (live)
An adult named Ryuichi Sakuma, turned by Swartz into Another Fourze as an "experiment" in 2011, after his previous powers began to fade. Sakuma kidnapped several 18-year-old schoolgirls of the Libra zodiac sign, and his "latest victim", Karin Yamabuki, defended him from Sougo and Geiz for unknown reasons.
It is later revealed that in 2003, while Sakuma was still a teenager, Karin had been hit by a car after he stood her up on a date. Ora then made a deal with him to revive Karin while he became Another Faiz—as his deal with Ora was still valid by 2011, he reverted to Another Faiz when defeated as Another Fourze.
With his Rider powers, Sakuma sacrificed 18-year-old Libra girls to give their life force to Karin.
- Arm Cannon: Instead of using Fourze's Rocket Module to perform charging punches as Gentaro did, he launches the energy copy of Rocket Module at enemies like a missile.
- Alas, Poor Villain: Without his Fourze and Faiz powers, Karin begins to fade away, and she tells him to live on without her, all as he cries his eyes out.
- Bat Out of Hell: Has devilish bat wings instead of the rocket wings from the actual Fourze.
- Casting a Shadow: His version of Crimson Smash has darkness mixed with the red of the Rider Kick.
- Chainsaw Good: Uses the Chainsaw Module for spin kicks as Another Fourze.
- Composite Character:
- He is actually two Another Riders in one, as hinted with his undersuit design. Even though Zi-O defeats him as Another Fourze using the Fourze Armor, he survives and it is revealed that he is also Another Faiz underneath the Fourze suit.
- Sakuma himself has elements of both Masato Kusaka and Ryusei Sakuta. The lengths he goes through to save Karin are reminiscent of Ryusei's efforts to save his best friend, and Sakuma's name is a reference to Ryusei. Meanwhile, he is a Ryusei School alumnus who is cannot function without a specific female classmate, who had previously died, and is driven to villainy, much like Kusaka.
- Dem Bones: Another Faiz has an obvious ribcage in his design - it's worth noting here that Gentaro and all Orphenochs were briefly clinically dead.
- Does This Remind You of Anything?: As Another Fourze absorbs a girl into a Astro Switch, he reacts as if he's just had a drug fix after a long time.
- Drunk on the Dark Side: Losing the powers of Another Faiz that would keep Karin alive, when Swartz came knocking with an additional Another Fourze Watch, Sakuma took it willingly.
- Earn Your Happy Ending: As Geiz had prevented Sakuma in 2003, the youth lives on to become an astronomer at a local observatory, thus providing Sakuma a normal life than hunting down innocent schoolgirls for 15 years. Until Hiryu came for his Another Fourze/Faiz powers.
- Epic Flail: His Chain Array Module is used as a flail.
- Foil: To Ryusei Sakuta/Kamen Rider Meteor, down to their names sounding similar. Both made multiple deals with devils and sought specific zodiac-related targets(Aries Zodiarts, 18-year-old Libra girls) to restore a close friend. However unlike Ryusei who matured and gained true friends in the process, Sakuma threw his life away to keep Karin alive, becoming a lone runaway who would constantly transfer Karin to a new school whenever things got awry for them while desperate for power to preserve her so as to not face her death for the 15 years that followed.
- Foreshadowing: The orange trails down the suit turning red and going all the way down to his feet are a subtle hint at what other power he has besides Fourze.
- Gatling Good: After recovering his Fourze form, he uses the Gatling Module to get away from Zi-O and Geiz.
- Longevity Treatment: His "treatment" is for his dead friend Karin instead for himself, is using the Life Energy of girls who share her age and Libra zodiac sign, and must receive these "life injections" regularly to maintain her form.
- Love Makes You Evil: He took on the powers of Another Faiz and later Another Fourze to sustain his girlfriend's life after an accident, ignoring the fact that she doesn't want him to.
- Macross Missile Massacre: Uses this for attacks and for his Smoke Out below.
- My Greatest Failure: He felt heavily responsible for Karin's death, and was originally fated to live the rest of his life wallowing in said guilt, according to Ora. This led to him take the chance to undo her death when Ora offered the power of Another Faiz to do so.
- Mythology Gag: The horns on Another Fourze's head bring to mind Kamen Rider Specter. In fact, in Kamen Rider Ghost: Legendary! Riders' Souls!, Specter uses the power of Fourze Damashii to destroy a resurrected Sagittarius Nova.
- Nightmare Face: Shows a gnarly snarl that looks like his Another Fourze form before transforming.
- Remember the New Guy?: Both he and Karin are Ryusei School alumni, but neither were even hinted at in 555 despite most of them being a close-knit group.
- Considering how the original timeline played out Sakuma probably didn't go to the reunion due to Karin's death and simply missed out the events of 555.
- Serial Killer: He used the power of Another Faiz to become this and gather life force for Yamabuki for 8 years before it started to fail and he was granted Another Fourze for the remaining 7 years of his 15 year murder spree.
- Shout-Out: Another Fourze's appearance is based of the Radar Button, an Uchuu Tetsujin Kyodain Monster of the Week.
- Smoke Out: He uses the Launcher Module to pull this move, having the missiles target the ground around him and create an obscuring explosion.
- Tragic Monster: Sakuma is definitely this due to spending 15 years as a serial killer to save his friend... That doesn't even want to be saved and contacted Kusaka to kill her to get him to stop.
- Transformation Is a Free Action: He constantly attempts to subvert the trope by attacking Sougo and Geiz while they are transforming. Later on, he attacks Sougo as Sougo is trying to activate the Fourze Ride Watch. During his fight with Geiz he grapples him to try to stop him from transforming and rushes him when he activates the Faiz Ride Watch.
- Wake-Up Call Boss: Not only is he the first Another Rider to be 2-in-1, Sakuma is also the first one to have a marked improvement in power over his original as he is capable of utilizing energy constructs based on the Astroswitches without the time delay of having to switch them out. The original Fourze needed Cosmic States to do something similar.
- The very next episode reveals that his 2-in-1 status means that if he has not taken on with the power of both riders he's comprised of, his Another Fourze form regenerates. He could only be permanently defeated by destroying him both forms in the years of his respective riders, simultaneously.
Another Wizard
Portrayed by: Zuimaro Awashima (live)
"As long as I had this power, things were supposed to go my way!"
A Shrinking Violet stagehand named Hayase who was given the power of Another Wizard in 2012 after accepting Heure's contract to save a small run-down family theater that belonged to his crush, Kaori. Using his new powers, he became a famous magician known as Wizard Hayase, and brought business back to the theater. However, after being told of Kaori's plans to move on in life with having the theater close down for good and getting engaged to the theater's previous star magician and current co-worker Nagayama, he goes on a power-hungry rampage for revenge.
- All Your Powers Combined: Unlike the original Wizard, he is able to use spells of different elements without having to change Styles, and uses just one ring for all of them.
- Animal Motifs: Fitting with the Rider he’s based off of, Another Wizard’s form is draconic in appearance.
- Broken Faceplate: His helmet design has a full-faced visor that is filled with cracks and shattered at the eyes, bringing to mind the image of a ring with a broken diamond. It could also be a representation of his Broken Tears and Shattered Sanity.
- Cessation of Existence: His Erase spell can erase an object from existence, like with the buildings in Beauty and Beast 2012.
- Character Development: After being freed of Another Wizard, Hayase is still happily doing magic in the Another Zi-O arc despite having been rejected by Kaori, implying that he is doing it now for himself.
- Dem Bones: His form is adorned with skulls and has a skeletal appearance.
- Did Not Get the Girl: His reappearance in #25 makes it clear that he didn't end up with Kaori, but that he's happier now that he's doing his magic for himself.
- Dishing Out Dirt: Another Wizard's Defend spell can erect a stone barrier to defend himself from enemy attacks.
- Drunk on the Dark Side: Once he starts using his powers to get revenge. Best shown with this quote when Geiz catches him attacking his coworker.Hayase: "Shut up! This power belongs to me."
- Earn Your Happy Ending: After being defeated, Sougo gave the present Hayase a chance to make a phone call to his past self in 2012, where he encouraged himself to pluck up the courage to confess to Kaori, even if it doesn't change her decision to marry Nagayama in the future. When Hayase is shown in #25 while not together with Kaori, he is happy working as a magician in a magic show restaurant till Hiryu attacks him.
- Entitled to Have You: The thing that hurls him into despair is the fact that his crush Kaori had just gotten engaged to his co-worker Nagayama after pondering over Nagayama's proposal for six whole years, while Hayase spent those six years being oblivious to this event and trying to win her favor with saving her father's theater through his magician stint, no less. The corrupting side-effects of being Another Wizard caused him to take his anger at this way too far.
- Forced Sleep: Another Wizard's Sleep spell can put his targets into a deep sleep. It can only be undone when Another Wizard is defeated.
- Gravity Master: His Gravity spell can alters the gravity of an object and propels it towards an enemy or alters the gravity of the target itself. It can also be used to allow himself to levitate.
- Gone Horribly Right: He used his newfound magic powers to save the family theater that belonged to his crush. He got it shut down anyways because she wanted to move on in life and away from the theater business while his co-worker felt it was holding him back from his true potential as a performer.
- Irony: The Rider he is created based off has a signature spell that saves people from despair known as "Engage", yet he himself falls into the Despair Event Horizon over an engagement that was not his.
- Loser Gets the Girl: Wants this to happen, but ends up being subverted because Kaori was already engaged. This of course, has disastrous consequences.
- Malevolent Masked Men: His helmet has a translucent visor that also covers his mouth. Another Riders before him all have their mouths exposed.
- Making a Splash: His Water spell can summon a massive torrent of water to attack the enemy, and Liquid spell can liquefy himself to make a quick getaway.
- Nervous Wreck: Being Another Wizard has taken its toll on his mental health, which only worsened after being attacked by Geiz.
- No Ontological Inertia: Since Another Wizard’s power was keeping Sleep’s effect active, his Ride Watch’s destruction also undoes Tsukuyomi’s charm.
- Playing with Fire: His Flame spell can manipulate fire just like the rider he's based on, allowing him to shoot several fireballs.
- Rage Breaking Point: When Hayase finds out that the theater he spent six years performing at to get Kaori's affection is closing down anyways, and she's getting married to Nagayama, to say he's pissed would be an understatement.Hayase: Who do you think I did this all for, damn it!?
- Single-Target Sexuality: He wants Kaori and only Kaori. And when he learns she's engaged to someone else...
- Squishy Wizard: Being a huge pushover in real life has led to Another Wizard relying extensively on his magic since he is not good at physical combat.
- Time Rewind Mechanic: His Rewind spell can reverse any damage done to an object, restoring it to its previous state, which he uses for his magic trick.
- Thinking Up Portals: His Connect spell can open a magical portal between two different locations.
Another OOO
Portrayed by: Tetsuya Iwanaga (live)
"True, I am Kuroto Dan. But, After I acquire the power of King, that name is merely an echo. Now I have become....KING KUROTO DAN!!!"
With the events of Kamen Rider Ex-Aid erased from history, Kuroto Dan, still a game developer with a god complex, was suffering a Writer's Block due to stress imposed onto him from his power-hungry father Masamune in 2010. Just then he was approached by Heure, who sought him due to his high levels of greed and desire, and was granted the powers of Another OOO.
With his mind warped as a result, he follows his father's footsteps in the form of a power-hungry conquest, killing him in 2016 out of spite and to ursurp his power. Establishing the Dan Foundation MegaCorp as part of his new goal of ruling the world, he calls himself King Kuroto Dan, and punishes people who defy him by turning them into or unleashing Waste Yummy-like monsters onto them.
For tropes pertaining to the original Kuroto Dan/Kamen Rider Genm, click here
- Adaptational Villainy: While Kuroto is already a villain with a bit of sympathetic traits in his home series, his appearance in this series amps up his villainy to the next level where he actually commits patricide towards his father, who is not a Kamen Rider in this altered timeline, out of spite to the point of having no sympathetic qualities whatsoever.
- And Then What?: While Kuroto is clearly a bad ruler from the start, Sougo develops his own perspective to why he is unfit to be king; Kuroto does not have a goal in mind when ruling over a country, only doing so for the sake of ruling.
- Big Creepy-Crawlies: Gives off this due to his leg armor being based off grasshopper legs.
- The Caligula: Anyone thinking that Dan would make a good ruler is probably insane. Sougo is initially open to serve under him to see for himself to see what he is really like, then opposes him once he's sure that he's indeed unfit to rule.
- Evil Counterpart: Ironically to himself. The original Kuroto was quite quite mad but ultimately all the dark things he did were because his view of himself and the world was so twisted he thought he was doing the right thing, best shown in Another Ending where he was legitimately confused as to why people weren't picking up arms and fighting the Zombie Gamers to save their loved ones...even if there were 6 people on the planet who COULD fight the Zombie Gamers. He also seemed to genuinely have an attachment to Emu and Poppy. Here, he's got none of these qualities and is just a power mad would be dictator, abusing his power for no ends but his own self-aggrandizing.
- Feathered Fiend: A given due to his head being based of the Taka helmet, complete with a dual wing-scarf.
- Forced Transformation: He can turn people into Waste Yummy-like monsters by throwing Cell Medals into their bodies, reminiscent of how the Greeed created the Monster of the Week Yummies back in OOO.
- History Repeats: In Another Ending, he killed his father when he becomes insane with the power of God, while enslaving the population as zombie-like Bugsters. In Zi-O, he once again kills his father after he becomes insane with the power of a "King", while enslaving those who defy him as the zombie-like Waste Yummies.
- Inappropriate Role Model: Sougo wants to be Kuroto's apprentice. Kuroto Dan...
- Or maybe not—he just want to see what kind of ruler Kuroto really is.
- Insistent Terminology: He is not an overlord. He is a king.
- Killed Offscreen: Not really killed, but seeing that Hiryu already had OOO, and anyone who made a contract in the past was taken to the hospital, this was his fate.
- Laughing Mad: As always.
- Motive Decay: Kamen Rider Zi-O greatly simplifies Kuroto's Start of Darkness, but considering Kuroto's Breakout Villain status and subsequent increased screen time in Ex-Aid came about by complete accident, this is Necessarily Evil to avoid
Continuity Lockout for a show that has been off the air for two years. - Mythology Gag:
- Another OOO is transformed from King Kuroto Dan. The first and original OOO was a King in a distant country in European region.
- He has several to Kousei Kougami from the original OOO series.
- When he first obtained his powers, he called it "Magnificentnote ", Kougami's Catchphrase to describe the birth of a new development.
- His megacorporation Dan Foundation is one to Kougami's Kougami Foundation.
- Patricide: Kuroto eventually killed his father to usurp his power.
- Red Herring: During his first encounter with Sougo and gang, he was assaulted by the sudden appearance of the Taka Watchdroid, causing him to drop a Genm Ridewatch. This, and the cracked display of his year of origin on his back, led Geiz and Tsukuyomi to believe he was created in 2016 and the key to defeating him was Genm's powers. The ensuing failed attempt to defeat him reveals to them he was actually created in 2010, which also meant that the Genm Ridewatch they had (dated 2016) was not the correct power required.
- Running Gag: Carried over from Ex-Aid, Kuroto continues to modify his name in hilariously minor ways. In this case, he just adds the character for "Oh/King" at the end of his name. This makes the "Oh" sound like an extension of "Kuroto", resulting in "Dan Kuroto Oh" coming off sounding as "Dan KurotOh". Over-Time translates this as "Dan KuroKing" to keep the joke.
- Scarf of Asskicking: Has a dual wing-scarf that also brings to mind the PuToTyra Combo.
- There's No Kill like Overkill: He has three sets of claws - His bladed fingers, a pair of large claws over his hands like the S.I.C. version of OOO's Tora Claws when deployed
◊, and a pair of folded Blade Below the Shoulder Wolverine Claws as per the original OOO's design. - Would Hit a Girl: He has no qualms about hitting Hina when she stood up to him.
Another Gaim
Portrayed by: Yuki Tomotsune (live)
A member of Team Baron named Asura who was kicked out of the group in 2013. Swartz then turned him into Another Gaim to allow him to exact revenge on the team. Using his powers, he imprisoned Kaito Kumon in the Helheim-like pocket dimension to take over Team Baron as its new leader, while subjecting its members and other people who do not agree with him to the same fate.
- BFS: Wields a large Zanbato as Another Gaim, in a similar shape to the DJ Gun in Taiken Mode.
- The Beastmaster: As Another Gaim, he has complete control over his Inves-like monsters.
- Braids of Barbarism: It's hard to see, but Another Gaim has about six black hair braids at the back of his helmet.
- Broken Masquerade: Thanks to Tsukuyomi and Sougo, Asura is forced to reveal his Another Gaim form in a public space, causing everyone, including his dance team, to run away screaming.
- Can't Take Criticism: Those who oppose him will be thrown into artificial Helheim along with Kaito.
- Eldritch Location: Another Gaim's artificial Helheim is just as eldritch in a different way compared to the original since it is implied that time there does not even pass at all since all the members trapped there still look healthy and unharmed despite in being trapped there for 5 years at max.
- Enemy Summoner: Another Gaim can summon Inves-like monsters from his artificial Helheim through the cracks he creates.
- Everything's Better with Samurai: Inevitable, being based on Gaim, along with including aspects of real life armor, such as hakama and a menpo mask.
- Green Thumb: Much like the Overlords, Another Gaim can use the plants of Helheim for combat, or to keep his underlings in check.
- Hate Sink: He may not be one of the worst Another Riders in terms of body count (his plan had zero casualties and everyone sent to Helheim was unharmed), but compared to the others he's one of the most unlikeable for just how nasty and self-centered his personality is.
- Hand Blast: Another Gaim can generate orange energy and launch it at his opponents.
- Impaled with Extreme Prejudice: Emulates the original Gaim's emblem with what looks like a blade stabbed through his head.
- It's All About Me: He thinks this way thanks to his rotten personality, which was only made worse when given the Another Gaim Watch. He threw Kaito and everyone who was against him into his artificial Helheim, and rules his Team Baron with fear.
- Killed Offscreen: Not really killed but rather assaulted, as Hiryu already had Gaim, and anyone who made a contract in the past was taken to the hospital, this was his fate.
- Meaningful Name: In Hindu and Buddhist mythology, Asuras were war deities exiled from heaven obsessed with power and approached any problem with violence. Asura himself was kicked out of Team Baron and uses violent methods to take over and keep his team in line.
- Never My Fault: Even though he had been sending people into another world to die, just because they disagreed with him, he blames Sougo for revealing that he was a monster, and stating that his last five years have gone down the drain because of him.
- Remember the New Guy?: He was never alluded to in the series beforehand by Kaito, though it is implied he was kicked out of Team Baron rather early in its time.
- Spontaneous Weapon Creation: Asura can manifest his zanbatō at will after transforming.
- Teleportation: Another Gaim can teleport himself to another location at will.
- Thinking Up Portals: As Another Gaim is based off the Inves Overlords, he can create and manipulate Helheim Cracks to banish people to his artificial Helheim. It also serves as the source of his Enemy Summoner ability.
- Tin Tyrant: A self-absorbed tyrant in rusted samurai armor, whose color makes it resemble a rotten orange.
Another Ghost
Portrayed by: Naotaka Horiike (live)
A police officer named Makimura whose sister Mika was originally fated to die from an accident in 2015. While Heure's time-stopping helped him reach his sister in time, he Refused the Call when the boy offered him the power to save his sister and become King, instead sacrificing himself to save her in the process. Nevertheless, Heure still forcibly resurrects him right after in a near-death state as Another Ghost for his plans.
- All Bikers are Hells Angels: While not actually having a bike, his design is meant to evoke one of a biker gang delinquent, ironically one of the polar opposites of a policeman.
- Brainwashed and Crazy: As Another Ghost, he obeys the Time Jackers' assignments of going around punishing potential "troublemakers" by absorbing their souls to prevent future accidents caused by them, out of a blind will of wanting to protect his sister from the accident that would have killed her. He later on gets further manipulated by Heure to use the power of the souls he absorbed to cause a rampage and have Sougo labelled as a future troublemaker that needs to be executed.
- Came Back Wrong: Another Ghost was transformed from the recently deceased police officer, revives him into a vigilante who hunts future accidents' "instigators" to prevent them from happening.
- Enemy Summoner: Another Ghost can summon any of the heroic Parka Ghosts or Gamma Commandos-like monsters to swarm his opponents.
- Earn Your Happy Ending: Thanks to Sougo and Takeru, Makimura and his sister Mika are saved from their fate of dying, and as a result, his Brainwashed and Crazy Vigilante Man status thanks to the Time Jackers never comes to be. Sadly, he is attacked off-screen by Hiryu for his Another Ghost power, and is sent to the hospital with the other Past Another Riders.
- Eyes Do Not Belong There: Has a small eye in his driver and a large Gamma-like eye in his chest. The bigger one is used to eat the soul he has absorbed and gain a power boost.
- Invisibility: Mixed with Intangibility, as he is a ghost, he can only be attacked by powers of Kamen Rider Ghost. He loses this after he is saved from his death, but turned anyway, now tangible, as shown when he is hit with the many attacks of the Ride HeiSaber.
- Killed Offscreen: Not really killed but rather assault, as Hiryu already had Ghost, and anyone who made a contract in the past was taken to the hospital, this was his fate.
- Mook: Can summon Gamma Commandos-like monsters to swarm his opponents with.
- Negate Your Own Sacrifice: Not willingly, as Heure undoes his act to save his sister by turning him into Another Ghost.
- Not-So-Well-Intentioned Extremist: His actions might seem extreme but he is saving thousands of lives by stealing the souls of a few "troublemakers"... If it weren't for the fact he is being brainwashed and used by the Time Jackers into doing their malicious bidding.
- Our Zombies Are Different: Not a zombie, a ghost, but alluding to Ghost's basic and upgraded forms being based on a funeral and Makimura's Came Back Wrong Almost Dead Guy status, Another Ghost resembles a rotten cadaver, with rotting flesh and green and red "veins" all over his arms.
- Sadistic Choice: Heure points this out to Sougo due to his status as a time-frozen Almost Dead Guy only kept alive by Another Ghost's powers - Either Makimura dies or Another Ghost keeps on living. Sougo takes a third option and has Takeru go to the past to save the siblings from their deadly accident. While Makimura still ended up becoming Another Ghost however, he is now well and alive at this point and thus they did not have to worry about his death upon defeat anymore.
- Scary Scarecrows: His torn clothing, ragged skin, and pumpkin-like head evoke this appearance.
- Scary Stitches: He can drop the hood like normal Ghost, revealing that his face is stitched into place.
- Shout-Out: His appearance is based off Venom of its 2018 film.
- Soul Eating: He has the ability to extract and consume other humans' souls.
- Tainted Veins: Has green and red "veins" all over arms.
- Vigilante Man: Becoming Another Ghost has caused him to actively seek out people who are destined to cause causalities, siphoning out their souls and leaving them dead.
- White Hair, Black Heart: Not on purpose mind you, but his white hair does nothing to hide the fact he is a soul-eating monster.
Past Riders made in Heisei Generations FOREVER
Another Double
Portrayed by: Kentarō Itō (voice)
An Another Rider who wields Kamen Rider Double's powers and serves Tid in an Alternate Universe where Kamen Rider is a television show, along with Another Den-O. His identity is never stated in the film, but according to Word of God the plan was for him to be a former Kamen Rider fan who became disillusioned with the franchise after the 2011 Touhoku earthquake.
- Body Horror: Takes a more grim version of Double's gimmick by being two bodies cut in half and crudely sewn together. Played further when his defeat ends up ripping him into his halves before exploding.
- Borrowed Catchphrase: Quotes "Now, count up your crimes!" from the original Double. Amusingly, when Sougo borrows (and subsequently mangles) that catchphrase while using the WArmor, Another Double calls him "half-boiled" — a line used by everyone except Shotaro.
- Broken Pedestal: According to Shirakura, he used to like Kamen Rider; but stopped after the 2011 Tohoku earthquake and tsunami because the Riders, being fictional characters, never came when people screamed for help. As an adult, he takes the Double Anotherwatch because he believes nothing that isn't real is worth celebrating, because they do nothing in the real world.
- Blow You Away: As with the original, this Double can control winds and make cyclones with his Another Cyclone half.
- Co-Dragons: Serves one with Another Den-O to Tid, but he is probably more responsible than Den-O.
- Eyes Do Not Belong There: If you look closely, you'll notice that his "ears" are actually the eyes of what appear to be Another Joker and Another Cyclone, Another Double's face apparently being made by sewing the two heads together back-to-back.
- Foil: The planned backstory described by producer Shirakura makes him a foil to Another Den-O (spoilers for the latter's identity): Both are fans of Kamen Rider who become disillusioned when they encountered loss in the real world, with Ataru losing Shingo and Another Double presumably being a kid who lost something in the 2011 Tohoku earthquake and tsunami. However, while Sougo is able to find a way to reignite Ataru's hopes, Another Double continued sinking into his hatred and grew up to become a monster that takes his suffering out on others.
- No Name Given: He is the first Another Rider whose human identity is unknown. Even the unnamed basketball player (Another Build) got more than him. In real life, producer Shirakura wanted to give him a human identity but was forced to scrap it due to time constraints. He finally explained the intended character concept on Twitter five years later.
- Rubber Man: Like the original Double, he is able to change his Cyclone half into Luna, which allows him to stretch his right limb. What makes this notable is that Another Double is the only example of an Another Rider having a form change ability.
- Scary Stitches: He evokes this with his design having his Cyclone and Joker halves being stitched together from head down his body in the middle.
- Shout-Out: His appearance is based off Baron Ashura of Mazinger Z.
- Technicolor Death: After being hit with Zi-O WArmor, his stitches come undone and his two half split apart, with his Another Cyclone half exploding in a cyan cloud and Another Joker half in a purple-black one, before the standard explosion.
Another Den-O
Portrayed by: Nayuta Fukuzaki (live)
Eventually finding out Shingo was kidnapped by Another Double for Tid on the day he was born, he follows Sougo into the past to prevent this, only to end up being turned into Another Den-O by Another Double, and brainwashed into assisting in his brother's kidnapping.
- All Just a Dream: He believes his meeting the Kamen Riders are all just a part of his own delusions to save himself from loneliness, due to them being a fictional work in his reality, and as such he lacks any true belief in them having any ability to save his brother. It gets to Despair Event Horizon levels when a retconned Kazumi refuses to save him from a bunch of mooks, causing him to lose all faith in Kamen Riders.
- Ascended Fanboy: In a manner of speaking. While Ataru is a fan of the Heisei Riders in general, he seems to be a fan of Den-O and Double in particular so it is oddly appropriate that he becomes the Another Rider version of Den-O.
- Big Red Devil: Unlike the normal design of Den-O, based off Momotaros and an oni, Another Den-O is clearly modeled after a western style demon, especially if those eye horns and an ancient Mayan-style belt buckle are any indication.
- Book Ends: The opening of the film shows a photo montage of him growing up as a Kamen Rider fan. After Shingo was rescued and returned home, a similar montage was shown again, only this time, it is Shingo and Ataru growing up together as fans.
- Borrowed Catchphrase: Upon transformation, he quoted Momotaros' infamous "I have arrived!" catchphrase.
- Brainwashed and Crazy: Ataru is not in control of his actions as Another Den-O, assisting in the kidnapping of his own brother Shingo.
- Co-Dragons: Serves one with Another Double to Tid, but Double is probably more responsible than he is.
- Cool Train: A given since he's based off of Den-O, as his Another Den-Liner can travel through time, and serves as Tid's base of operation.
- Curb-Stomp Battle: On the receiving end of one when he and Kamen Rider Den-O make contact during the film. All of the Imagin pile-drive him with each of their individual Forms one by one.
- Clothes Make the Superman: A given with all Another Riders, but Den-O takes the cake, especially when the faceplate unmasks itself to be revealed to be Ataru, revealing that he is still physically fine and it really is just armor.
- Earn Your Happy Ending: With Tid dead, Shingo saved and with the knowledge of all 20 Heisei Riders, Ataru grows up with his older brother at his side, and ensures the future of Kamen Rider in general.
- Eyeless Face: His horns replace his own eye sockets.
- Irrational Hatred: Justified that in being Brainwashed and Crazy, Ataru becomes a Kamen Rider-hating minion of Tid.
- Light Is Not Good: Despite having a white palette, Another Den-O is an evil monster with a hatred of all Kamen Riders.
- Loss of Identity: Inadvertently causes this in two ways:
- First was when he made the wish on the Imagin Futaros and summoned the Riders into his reality, but due to Futaros’s lack of power, it causes said Riders to be retconned and eventually be sent back when he loses faith in them. Had it not been for the W Watch, Tid may have gotten away with ruling his world as Another Kuuga.
- The other is when he shows Sougo and Sento his collection of Rider figures and explains how they're just a TV show in his world. This causes poor Sougo to have an identity crisis, though Sento manages to keep him going by telling him about his own history. Though when the movie is over and they still find themselves in Ataru's world, they decide not to question it and just live.
- Never the Selves Shall Meet: Averted. Ataru meets Another Den-O when Shingo gives himself up in the present, who reveals his face to him. It comes full circle later on just after being turned into Another Den-O, when he chases the then-escaped Shingo into 2018, he meets his past self and reveals his face to him.
- Reforged into a Minion: Without spoiling his host, this is his origin when subjected to said treatment by Another Double when jumping with Futaros into the past (January 29, 2000).
- Shout-Out: His appearance is based off Oni Momotaro a character from Momotaro Jigoku-hen, a Ken Ishikawa manga.
- Significant Birth Date: Ataru's birth date is January 29, 2000, the day before the premier of Kamen Rider Kuuga. His Imagin, Futaros, uses this as a way to get into the past in an attempt to save his brother Shingo.
- Super-Speed: One of Another Den-O's abilities is to run at a blinding speed as means of retreating, leaving an after-image of himself behind.
- Walking Spoiler: In the movie, it is hard not to spoil who is Another Den-O without the fact that he and his human host appear at the same time.
Another Kuuga
Portrayed by: Shunsuke Daitō (live)
With the ancient Kurogatake ruins materialized into Ataru's reality as a result of Futaros's power, Tid visits the ruins to steal the power of Kuuga from the mummified corpse of the original Kuuga, Riku, producing the Another Kuuga Anotherwatch which he used on himself. He eventually uses it on Shingo as well, fusing both of them together into the evolved Another Ultimate Kuuga.
- Ascended Fanboy: In a twisted manner, Shingo, as a huge fan of Kamen Rider Kuuga, is this once Tid absorbs him into Another Ultimate Kuuga.
- Attack of the 50-Foot Whatever: Another Kuuga is huge (on par with at least the Time Mazines), being composed of all CGI (not unlike Kamen Rider Core), easily being the largest Another Rider in the show (assuming that there isn't an Another J).
- Big Creepy-Crawlies: Especially taking the stag beetle motif a step further.
- Dark Is Evil: As Another Ultimate Kuuga, Tid fits this trope when Yusuke Godai displayed otherwise.
- Foreshadowing: Another Kuuga foreshadows a decent part of the endgame of the show in his appearance.
- His evolution into Another Ultimate Kuuga reveals that Another Riders can gain forms based on their source Rider's enhanced forms, something that would make its way into the show with Another Zi-O II.
- Tid became Another Kuuga by directly taking Kuuga's power from Riku's Arcle Belt and having Another Double and later Another Den-O as his minions. Swartz similarly becomes Another Decade by directly stealing Tsukasa's Decade powers from him and has Ora as Another Drive as his minion.
- Kaiju: Another Ultimate Kuuga makes him even bigger than Another Kuuga, and his monstrous appearance makes him look more like an Ultra Series monster than a Kamen Rider one.
- Mook Maker: After becoming Another Ultimate Kuuga, Tid can fire a dark cloud from his chest and summon Masquerade Dopants, Waste Yummies, Dustards, Ghouls, Elementary Inves, Low-Class Roidmudes, Gamma Commandos, Bugster Virus, Guardians, and Hard Guardians.
- Laughing Mad: After becoming Another Ultimate Kuuga, he laughs, madly, as he's obliterating everything in sight with his laser breath.
- Multi-Armed and Dangerous: After becoming Another Ultimate Kuuga, this trope is definitely in effect.
- One-Winged Angel: Unlike the other Another Riders, Another Kuuga is giant and more monstrous, requiring a Time Mazine to fight it. It gets worse when he becomes Another Ultimate Kuuga.
- Powered by a Forsaken Child: Basically how Tid obtains Another Ultimate Kuuga.
- Rasputinian Death: It takes a lot to bring down Another Kuuga:
- In his first form, it takes a double Rider Kick from Zi-O's Time Mazine powered by Kuuga and Geiz's Time Mazine powered by Build. The Anotherwatch is still intact despite the defeat, and then Tid merges with Shingo to become Another Ultimate Kuuga.
- Then, as Another Ultimate Kuuga, he gets slammed by Geiz's Time Mazine, and gets Rider Kicked by every primary rider with a finale of a triple Rider Kick from Zi-O, Build, and Kuuga.
- Super Mode: After absorbing Shingo into his body, Another Kuuga powers up into a form more reminiscent of Kuuga's Ultimate Form than his regular Mighty Form.
- Weather Manipulation: As Another Ultimate Kuuga, dark clouds beging to suround him, which might seem weird, until you realize that N-Daguva-Zeba could also do something like that as well.
Future Riders
Another Shinobi
Portrayed by: Hideya Tawada (live)
An Another Rider produced from Rentaro Kagura in present-day 2019 after he accepts Heure's contract to gain the power to protect the weak, negating his future of becoming the actual Kamen Rider Shinobi himself in 2022. The Another Watch Heure used on him was obtained from Swartz, who took the powers away from Rentaro's own future self.
- Armor-Piercing Question: Sougo asks Kagura if he really wants to be a king. Kagura’s answer? No, he does not want to be one.
- Being Good Sucks: The reason he took up the request to become Another Shinobi in 2019; for all his sense of justice, he was too weak to actually save anyone. He later grows out of it thanks to Sougo.
- Blow You Away: He can generate purple cyclones for defensive or offensive means, and is powerful enough to to reflect DeacadeArmor Ryuki Dual Time Break.
- Bully Hunter: Of the serial killer kind. With the power of Another Shinobi, he uses his elemental ninjitsu to get back at thugs who attack him and his friend.
- Casting a Shadow: Can leap and hide within a shadow.
- Combat Parkour: Similar to his future self, he is capable of back flips as well as other moves, showcasing his athleticism.
- Dem Bones: Just as Another Wizard, his form is adorned with skulls and has a skeletal appearance.
- As it is revealed in Rider Time: Shinobi, this is because his appearance is based off Niji no Hebi's leader Yaminin.
- Dishing Out Dirt: Can generate sand that buries one of the thugs alive while his driving in his car.
- Earn Your Happy Ending: After being encouraged by Sougo to trust in his own strength more than the Another Rider powers he was given, he tries to stop Swartz from re-activating his Another Watch a third time to allow him to stand up and fight for himself.note Swartz ignores his plea however and still re-activates his Watch anyways.
- Elemental Powers: He still has access to his Ninjutsu, and uses the elements to get back at the thugs who harmed his friend.
- Make Wrong What Once Went Right: In Geiz Revive’s timeline, Rentaro became the Kamen Rider of 2022. This Rentaro however, was approached by Heure years before becoming a Rider to turn him into Another Shinobi to prevent him from becoming Kamen Rider Shinobi in the first place.
- Subverted in the end, as becoming Another Shinobi led Rentaro to meet Sougo, whose encouragement gave him the courage he needed to fight as Kamen Rider Shinobi in the future, setting in stone his fate as a future Kamen Rider (while this allowed the Shinobi Miridewatch to be produced).
- Making a Splash: Another Shinobi can generate water at such a large volume, it drowns another thug when he is indoors.
- Playing with Fire: Can manipulate fire as part of his elemental manipulation.
- Technicolor Fire: The flames he produced are purple in color.
- Shout-Out: His appearance is based off Hattori Hanzō a character from Shadow Warriors, a 1980 show.
- Stuff Blowing Up: His fragoportation, the ability to teleport an item away with an explosion, which he uses to intercept a thug that rode a motorcycle.
- Wolverine Claws: His Another Tekkō-kagi, which look more like metal claws on his arms then actual weapons.
- Yellow Eyesof Sneakiness: His yellow visor gives his "eyes" this appearance.
Another Quiz
Portrayed by: Yoichiro Saito (live)
Mondo's father, Tamotsu Douan. A devoted scientist and researcher who was originally so obsessed with his work he had neglected his family, and was fated to have died without any achievements despite his efforts. Ora approached him in 2019 to offer him a chance to change his fate for a brighter future. Accepting her offer, he becomes Another Quiz to steal other scientists' knowledge to further his own research.
- All for Nothing: In Geiz Revive's timeline, despite abandoning his family for the sake of his research, he died without ever achieving anything.
- Catchphrase: "Give me your knowledge."
- Earn Your Happy Ending: Thanks to Geiz and Quiz, Tamotsu manges to remember just why he ignored his family, and while Ora still re-activates the Anotherwatch, and the Quiz Miridewatch is still created, Mondo's watch finally starts moving, implying he may have changed his family's fate after all.
- Evil Is Visceral: Playing off his counterpart’s knowledge motif, Another Quiz is a walking pile of wired brains. His thigh armor also resemble vertebrae.
- Foil: To Geiz. Both were fated to die having accomplished nothing worth noting with their lives, but offered a chance to get the future they were obsessed with through a Deal with the Devil (Ora for Another Quiz, White Woz for Geiz).
- Impossible Thief: His Intelligence Transfer allows him to steal the knowledge from other scientists. The problem is that seems to be the only thing he can do as Another Quiz.
- Joke Character: Another Quiz has absolutely no special capabilities besides his Intelligence Transfer, not the Armor-Piercing Question power his son has, nor any other known abilities. The only reason he even stayed around the Quiz Arc was because of the fighting between Geiz and Quiz. The moment the two team up, he goes down. Unfortunately, the original Quiz cannot destroy the Another Quiz Watch; only the power of the Quiz Miridewatch can, which White Woz creates in the confusion, and uses it to sadistically finish him off.
- Kick the Dog: He is subjected to particularly brutal one thanks to White Woz, being told ruthless "questions" while Woz laughs at the poor man's suffering. It is enough to make you really feel sorry for him.
- My Brain Is Big: His entire body is one.
- Parental Abandonment: In Quiz's timeline, he would throw himself into his work and even left his family as a result. It is even implied that Quiz never really got to know his father before his death. Ironically, he did care, as all his work was to save his wife.
- Sigil Spam: Less evident than Quiz, but he is also covered in question marks, albeit faded.
- Shout-Out: His appearance is based off Hats in UltraQuiz, a Nippon TV quiz show
- Your Princess Is in Another Castle!: Contrary to what Geiz thought, the original Quiz cannot destroy the Another Quiz Watch; only the power of the Quiz Miridewatch, which White Woz creates in the confusion, can do so.
Another Kikai
Portrayed by: Rihito Itagaki (live)
A mysterious Another Rider of unknown origins who was created not from an Another Watch, but instead from a stick insect-like parasite that makes up the Rider's "horns", which escapes to hijack and transform another living body into Another Kikai whenever its current body is defeated.
In an attempt to gain and control its power, Swartz picks up the parasite and fuses it with Heure, in the hopes that by fusing it with a Time Jacker he could stabilize its power and produce an Anotherwatch from it for his use.
- Animated Armor: Unlike other Another Riders, Another Kikai by itself can operate just fine without a human host, since it is basically a wooden machine. It just works better possessing a host, which Heure gets to learn the hard way.
- Achilles' Heel: Having the same virtual keyboard generated from touching its chest that Kamen Rider Kikai has, its powers can be unlocked for use after entering the correct password. In this case it is "WILL BE THE KING", a phrase found written on Sougo's old toy robot. This allowed Kamen Rider Woz to produce a Kikai Miridewatch from it to defeat it permanently. Or in an averted future, allowed Ora to produce a proper Kikai Anotherwatch which she continued using on Heure, who went berserk even further and killed Tsukuyomi.
- Elemental Punch: It can generate electrified ice energy and execute two of Kikai's finishers, Kikai Will Destroy and Fullmetal The End.
- Explosion Propulsion: It can generate energy from its hands and launch itself in the air.
- From a Single Cell: Even if it's wrecked by Zi-O II, so long as the insect ornament of Another Kikai can survive, it can possess another organism to reform itself. A tree will do as a host in a pinch, but a human, especially a Time Jacker, works much better.
- Glass Cannon: With a tree for a host, while Another Kikai's attacking power is about on par with other Another Riders, it goes down in a single hit from just about anything. Its ability to respawn, however, makes this property only an inconvenience.
- Godzilla Threshold: After Swartz makes the insane move of using Heure as Another Kikai's new host, everyone else drops their fighting to team up against it out of agreement that whatever this thing is, it has to be killed now. The battle against it marks the first time that Zi-O, Geiz, and White Woz unite against a common foe.
- Humanoid Abomination: Even by the standards of Another Riders. Nobody knows what Another Kikai is, who made it, or why, just that it has to be gotten rid of by any means necessary. The only person who is enough of a maniac to actually try and control it is Swartz. It turns out, Another Kikai was in fact a Time Paradox monster created by Sougo, due to the creation of Future Rider Kikai.
- Irony: The original Kikai is themed around machinery and robots, and has a good heart, willing to defend humanity, whom he was supposed to kill. Another Kikai flips these motifs around as a bizarre wood golem, and is a heartless Temporal Paradox monster that wildly attacks everything around it, even managing to kill Tsukuyomi in an alterante timeline.
- Killed Off for Real: The Kikai parasite turns to ash after getting hit by Full Metal Break/Bakuretsu DeLance.
- Macross Missile Massacre: Another Kikai can create and launch multiple missiles from its body, best shown in an averted future where it killed Tsukuyomi.
- Nonstandard Character Design: Unlike the other Another Riders, Another Kikai's design is less based on the robotic Kikai and moreso a wooden replica that vaguely resembles the original.
- Shout-Out: His appearance is based off Pinocchio, the fairy tale about a wooden boy.
- Stealth Pun: Its bizarre design motif seems to be based off a joke on the Japanese kanji for "machine" (機械 Kikai) containing the kanji for "wood" (木 Ki).
- Unwitting Test Subject: Heure was used as a host for the parasite by Swartz in an attempt to create Kikai Anotherwatch for his own use. And in an another timeline, with Ora's help, he succeeds.
- Wrong Context Magic: Another Kikai operates on a completely different system, being born from a living Puppeteer Parasite that creates bodies from other living things such as trees, instead of being made from a human using an Another Watch. It is due to this that Swartz made Heure its latest host in the hopes that this would convert the powers into a Watch system that he can control.
Past (and Present) Riders made in the Present
Another Ryuga
Portrayed by: Takamasa Suga (live)
Shinji Kido's Mirror World counterpart Dark Shinji, who embodies his grudge for his previous journalism company ORE Journal having shut down for good. As such, he accepts Heure's contract in 2019 to become Another Ryuga as a means to travel into the real world and attack followers of the now-defunct news site out of revenge.
- Attack Reflector: He is able to reflect attacks back using a dragon shaped mirror.
- Beyond the Impossible: Another Ryuga is so powerful that White Woz using the Quiz Miridewatch asked if he could beat Another Ryuga, the Miridewatch rebounded. Quiz's power should damage opponents based on the question asked by its user who decided the right answer, but even the watch couldn't imagine White Woz winning.
- Cool Sword: He wields a larger version of Ryuga's Drag Sword.
- Dark Is Evil: He is essentially a black Ryuki and evil as well.
- Evil Sounds Deep: His voice is much deeper than Shinji's and is also very evil.
- Failure Is the Only Option: The mere act of fighting him is this. His host exists in another reality that can't be accessed normally, which he can phase into through any reflective surface. His powers are based on a Rider from a timeline that no longer exists and thus creating a Ridewatch to defeat him isn't possible. Worst of all, any attacks leveled against him will be countered by his Attack Reflector mirror powers while negating any damage done to him. This also means that if someone were to use a Finishing Move against him, he'd survive it and the backlash would kill the attacker. The only way to defeat him at all is to do the unthinkable and kill his real world counterpart, an innocent civilian. Or use the game breaking power of Zi-O II.
- Left-Handed Mirror: Another Ryuga noticeably weilds his sword in his left hand, contrasting Another Ryuki who weilds his sword in his right hand. Fitting for a mirrored reflection of Ryuki.
- Missing Reflection: According to Rider Time Ryuki, he doesn't show up in reflections on his side of the Mirror World. Which makes sense when you realise that he IS the reflection.
- Power Fist: He wields a sinister version of Strike Vent Drag Claw gauntlet, only it's a great deal more ornate than simply Dragblacker's head.
- Screw This, I'm Out of Here!: When Ryuga gets curb-stomped by Zi-O II, he attempts to flee, only to have every exit for him be destroyed by Sougo's Haou Giri.
- Sdrawkcab Name: His label on his chest indicating his name and year of origin "2002" on his right and "Ryuga" on his left are horizontally flipped. In #21, the name label was smudged, leaving only "Ryu", making it look like he's Ryuki, not Ryuga.
- Technicolor Fire: Dark Shinji can generate black flames from his dragon head gauntlet.
- Wrong Context Magic: Due to the nature of Ryuki's canon, he is canon and at the same time, he shouldn't exist since his timeline was one of the many Alternate Timelines due to Kanzaki's abuse of Odin's Time Vent, making it impossible to even get his Ridewatch or the actual year he was made in the first place since Time Mazines can only go to places in time in the main timeline. Further playing on this is the fact that due to the nature of the Mirror World as Another Dimension, there is no way for anyone to be able to cross over to that world to pass Dark Shinji a Blank Watch or retrieve it from him for use when the time comes.
Another Zi-O
Portrayed by: Yu Sakuma (live)
Young Hiryu Portrayed by: Taiga Komie
"Live for the present? Don't make me laugh! You have no idea what a tragedy this has been for those who weren't chosen! Which is why I have a test for you: can you still spout that same nonsense... after I've taken everything from you?"
Spoiler
"Everything would have been fine if I wasn't born in the Heisei Era. That's why... I'll erase Heisei, and there's no need for Reiwa Either. I have become the Ruler of this era, and I decree the current year shall be known as... Showa Year 93!"
A mysterious young man named Hiryu Kakogawa who was given the power of Another Zi-O in 2019 by Swartz. He seeks to defeat Sougo, accusing him and Tsukuyomi for the death of his parents during a bus accident they were involved in that costed both of them their parents in 2009. As Another Zi-O, he is referred to by Swartz as the "King of the Dark Riders".
He later returns in an altered timeline where he replaces Sougo as the one destined to be Oma Zi-O, his powers having evolved to allow him to transform into Another Zi-O II, with powers rivaling Grand Zi-O. He seeks to break Sougo by as payback for his statement of "Live for the present."
He later returns again in Kamen Rider Zi-O Final Stage as Kamen Rider Barlckxs. He sought out to collect the 7 legendary Showa Ridewatches. After collecting them, he became Another Ohma Zi-O.
- All Your Powers Combined: Just as Sougo and Geiz can use the powers of previous riders, Another Zi-O can use the powers of the Another Riders that have been defeated up until now. He does this by directly absorbing their power from the hosts.
- Big Bad: After spending the entire series being a puppet for the Time Jackers, he finally becomes the big bad for real in Kamen Rider Zi-O Final Stage after collecting the 7 legendary Showa watches and becoming Another Ohma Zi-O.
- Big Bad Wannabe: Hiryu has the bad luck of debuting in the same arc as Geiz Revive, who has the power to kill Oma Zi-O. Once they meet, Hiryu falls behind and struggles to keep up. He doesn't even make it to the end of the larger Day of Oma arc, being defeated in the third-to-last episode of the arc. Even in the Another Zi-O II arc where he become the overlord in Sougo's place, he is completely under Swartz's thumb and doesn't realize it. The arc ends with Swartz cutting him loose when he has served his purpose, and is not seen again until his return in Final Stage.
- Boomerang Bigot: Final Stage has him briefly slip, as part of his Motive Rant, that he despises everyone else in his generation, not just the Heisei Riders that keep beating him up, for not having the strength to overcome the market crash that occurred early into the Heisei era.
- Born in the Wrong Century: To truly demonstrate how petty and wretched Hiryu is even without Swartz stringing him along, Hiryu continues to shoot for world domination in Final Stage using this as an otherwise laughable motive, saying that he believes his strength proves he should've been born in Showa while also throwing in strangely political snark about how his generation couldn't handle the market crash of 1992.
- The Brute: He's really only useful as extra muscle for Swartz and his allies. While he's the one nominally in charge of the world as Zi-O II, he's easily beaten by Diend. Once he loses the Zi-O Anotherwatch, Swartz abandons him on the spot.
- Butterfly of Doom: Swartz changing time resulted in Hiryu ultimately rising up as Oma Zi-O in Sougo's place.
- Came Back Strong: As a result of Swartz screwing with time, Hiryu comes back as Another Zi-O II and as the new demon king.
- Combat Clairvoyance: As the Another Riders copy all of their counterpart's abilities, he has Zi-O II's despite resembling Zi-O's base form.
- Dark Is Evil: Gains black royal robes as the new Demon King after Sougo distorts time.
- Disc-One Final Boss: Despite being built up as Swartz's last resort, having a personal connection and history with Sougo, and awakening as the Day of Oma seems to be on the horizon, his debut and defeat only occur a little beyond the halfway point of the series. Though the regeneration of his Ridewatch, along with time being distorted, allows him to become Another Zi-O II and the new Oma Zi-O... Until it's made clear that even then, he's just a pawn to Swartz's greater scheme of stealing Decade's power for himself, and once he loses, this applies to him, again, until Final Stage, where he becomes Another Ohma Zi-O.
- Dual Wielding: He wields two blades which hints that he has the same powers as Zi-O II.
- The Dragon: Ultimately, he's this to Swartz. While he thinks otherwise, he's really doing everything Swartz asks him to while Swartz is nominally subservient to him.
- Enemy Summoner: Due to having all the Anotherwatches, he can remake the Another Riders as shown in episode 27. In the next episode, he has remade Anothers Build, Ex-Aid, Faiz, Fourze, Wizard, Gaim, Ghost, and OOO. This improves even more as Another Zi-O II, to the point where he doesn't even need a host and can simply summon them with a thought. By 2019: Tsukuyomi Confidential, he can summon every Another Rider minus Ryuga, Decade, Drive, and the Future Riders.
- Evil Cannot Comprehend Good: After Sougo and Geiz together beat Hiryu in episode 28, Sougo apologizes to Hiryu, saying that he can't change the past and Hiryu has a right to hate him, but Hiryu can't live his life focused only on the past and he knows Hiryu can get past it. The Another Zi-O II Arc reveals that Hiryu couldn't accept Sougo's good will and instead grew to hate him more, making it his mission to steal everything from Sougo out of spite and, as he would imply, envy that he still has a better fate than him.
- In Final Stage, He ultimately considers himself as Born in the Wrong Century and attempts to wipe out the Heisei and Reiwa eras, allowing the Showa era to continue while erasing the other Riders' powers in the process. However, the Riders from The First,The Next, and Amazons manage to remain intact because they consider themselves as Showa Riders created in Heisei, to which he dismisses it as Heisei and Reiwa being the eras they're supposed to be. The final battle also has him stubbornly tell Sougo his belief that those like him who aren't chosen by fate can only hang on to the past, but Sougo rebuffs this by saying that time only moves forward and can't be turned back. So as long as holds on to the past, he'll always lose against him.
- Evil Counterpart: To Zi-O, naturally. He even uses a black version of the Ziku Driver rather than a twisted replica like the others.
- In Final Stage, he takes the forms of Zi-O's other Evil Counterparts, Barlckxs and (Another) Oma Zi-O.
- Evil Is Petty: The entire reason he's terrorizing the world in the Another Zi-O II Arc? Just to steal everything from Sougo. On top of that, he frames the entire thing as a test to see if Sougo would still profess the same ideals after losing everything. When at the end of the arc Sougo still does, Hiryu is furious. Final Stage also has him attempt to destroy the Heisei (and Reiwa) era(s) after coming to the conclusion that he would have been better off not being born in Heisei, but only mentioning how he lost to the power of its Riders, and how the whole generation was weak enough to fall to things like the 1992 market crash.
- Eviler than Thou: The Another Zi-O II Arc reveals he is worse than Ohma Zi-O. Ohma Zi-O might be ruling the world with an iron fist but he honestly believes his actions somehow saved the world even if he is completely insane. Hiryu willingly become the Overlord and is terrorizing the world because he wants to take everything from Sougo. Final Stage has him actually become Another Ohma Zi-O as part of his plan to wipe out the Heisei and Reiwa eras from history (which could also help him finally defeat Sougo in the process).
- The Faceless: In Final Stage. He only appears on stage as a hooded figure that becomes Barlckxs and Another Ohma Zi-O.
- Fatal Flaw: Wrath. His hatred of Sougo is so potent it drives him to destroy the world in an alternate future just to spite him. What he does not realize is Sougo had nothing to do with the accident that ruined his life, and he's being played for a fool by the guy who ACTUALLY caused the accident, Swartz. Final Stage has him take it out on the Heisei era as a whole, believing he was unlucky enough to be born in what he considers to be a weak generation of people.
- Also Envy. He considers it unfair that fate has apparently chosen Sougo to be rewarded in some form or another, while leaving others like him to suffer as a result of the process. So he plans to make Sougo and anyone else experience his loss by taking away whatever was supposed to be theirs for himself, finally establishing his superiority.
- Freudian Excuse: He lost his parents in an accident 10 years ago. Thinking that Sougo did it, he decides to get back at him. However, the ways he chose to do so are disproportionate, misplaced and above all, petty. Thus, his excuse, while making him a Tragic Villain, doesn't makes him a sympathetic individual.
- Godzilla Threshold: He is this for the Time Jackers, because as bad as Ohma Zi-O is, having Another Zi-O possibly become Another Ohma Zi-O that isn't under their control is far worse. Heure and Ora were horrified that Swartz used the Zi-O Anotherwatch, while Swartz looked desperate enough to use it when the signs that The Day of Oma were coming sooner then expected. Hiryu succeeds in such an endeavor in Final Stage, but it doesn't end well for him.
- Based on comments by Heure in episode 26, this seems to be because it means that Hiryu himself is likely to just become Ohma Zi-O, rather than a pawn they can manipulate. 2019: World Reset shows that he wasn't kidding.
- Grumpy Old Man: Though Hiryu's obviously a young adult like Sougo is, his motivation and one-time snide political comment in Final Stage gives him the fully-fledged mentality of an old man talking about how things were better back in the day.
- Irony: For all his talk of being Sougo's rival and becoming his Another Rider counterpart, Hiryu is little more than a stepping stone for everyone else in the grand scheme of things, whether it be actual threats such as White Woz attempting to have Sougo killed and Swartz stealing Decade's powers, or Sougo's own allies growing to trust him, such as Geiz realizing he doesn't have it in him to kill Sougo and Tsukasa leading Sougo to strengthen his resolve to become king.
- In Final Stage, part of his goal to destroy Heisei and create an eternal Showa era involves him becoming Barlckxs, who is based on the last Rider to be made during the Showa era and whose series continued airing at the start of Heisei.
- It's Personal: Hiryu thinks that Sougo caused the bus accident 10 years ago and is determined to defeat him as a result. He also saw Sougo's statement of "living for the present" as an insult, with him becoming Another Zi-O II and new demon king, just to get back at him for that.
- Lack of Empathy: Hiryu is so twisted by his hatred of Sougo that all he cares is that Sougo suffers no matter the consequences. First he assaults the former Another Riders to gain their remaining powers that puts them in comas then realizing that he's lacking the power to defeat Sougo and Geiz Revive, he turns innocent people into Another Rider army. And once time has changed so he is the overlord instead of Sougo, he is willingly doing it just to make Sougo suffer by taking his future as the worst overlord of all time, not caring about the regular people that will suffer for it. Final Stage has him dismiss people in Heisei as a weak generation for how they were affected by things like the market crash.
- Light Is Not Good: In contrast with Zi-O's Dark Is Not Evil, his suit is white, but he is still an Another Rider.
- Meaningful Name: His last name, while spelled differently, can be read as "River of the past". Also like with Tokiwa Sougo being named after a famous place, Kakogawa is a famous city in Hyōgo Prefecture.
- Mirror Character: Despite viewing each other as pawns for their own goals (with only one of them actually being right), he shares a lot in common with Swartz than either of them would care to notice, especially considering how Swartz did cause the accident that killed his and Sougo's parents in the first place. Both are motivated by how fate screwed them over and are determined to achieve their ambitions, which include the petty goal to spite who they deem responsible for their misery. Caring for no one else's lives but their own during the process. The main difference is that Hiryu is ultimately still a Tragic Villain and the actual Unwitting Pawn in the grand scheme of things, considering once again that Swartz was the one who was really responsible for everything Hiryu went through since, ironically turning him into someone like himself.
- Mirror Match: Due to Hiryu having all of Zi-O's powers including Combat Clairvoyance, Sougo and Hiryu's fights always end in draws due to their powers countering each other. Black Woz even states that Hiryu can be considered Zi-O II's Achilles' Heel. This continues as Another Zi-O II vs Grand Zi-O.
- My Rules Are Not Your Rules: For some reason, he is able to get a Riderman watch to eject from the fifth Another Faiz in Final Stage, without any regard for the fact that it isn't the right Ridewatch, nor the fact that this Another Faiz isn't any incarnation of Joji Yuki. The only explanation possible would be that Faiz is the fourth Heisei Rider and Riderman is the fourth overall Kamen Rider.
- Mythology Gag: His helmet design actually takes considerable inspiration from Kamen Riders 1, 2 and the Shocker Riders, with a pair of red bug eyes behind the visor, a jagged mouthpiece, and the metal piece in the middle of his head.
- Never My Fault: His most consistent character trait is his inability to accept that his problems are his own fault, instead blaming anything else he can for his misfortunes (possibly because the accident that started them really was something beyond his control). As of Final Stage this has escalated to blaming the entire Heisei Era itself for his problems (implied to be for similar reasons as Quartzer).
- No-Holds-Barred Beatdown: Final Stage has Hiryu succeed in becoming Another Ohma Zi-O, but is quickly met with the real Ohma Zi-O and Zi-O Ohma Form beating the crap out of him.
- Not Brainwashed: While all the Another Rider hosts were brainwashed, corrupted, or convinced to become Another Riders, Hiryu does it willingly. Happens again in episode 41 when time is changed and erases Sougo's existence which causes Junichiro, Tsukiyomi and Geiz to completely forget him. But when Hiryu meets Sougo again, he reveals he not only remembers Sougo but is ruling as the Overlord simply to spite Sougo.
- Not Quite Dead: Unlike all other cases of defeating an Another Rider, the Another Zi-O Ridewatch survives the King Slash finisher not because it wasn't destroyed, but because it remade itself following its supposed destruction.
- The Only One Allowed to Defeat You: Due to thinking that Sougo caused his parents' death, he is determined to defeat Sougo himself. When Geiz interferes in his fight with Sougo, he starts to attack Geiz Revive... It goes about as well as you would expect.
- Our Founder: In the alternative world where Sougo is Ret-Gone, Hiryu has a similar statue to the one Oma Zi-O put up in 2068 but with the Another Riders taking the place of the original Riders.
- Post-Final Boss: In Final Stage, with the series' other main villains already taken care of at this point, all that remains is him leading the Quartzer Riders as the new Barlckxs, eventually becoming Another Oma Zi-O.
- Power Copying: Another Zi-O copies the powers of the original Zi-O himself, but instead of wearing armors, he fully changes into previous Another Riders as his forms by inserting their respective Anotherwatch into his belt.
- Puppet King: He has been stated to be the king of the Another Riders and yet has been played for a fool by the same man responsible for the death of his parents.
- Pyrrhic Victory: Congratulations, you've collected the seven legendary Showa Ridewatches and become Another Ohma Zi-O. Too bad Zi-O Ohma Form and Ohma Zi-O are standing right there. Sure, it was because they had some help from different versions of 1, 2, and V3, plus Amazons Alpha and Omega, but still.
- Red Baron: He is also called "He who will unite all Another Riders", as well as "The King of Dark Riders."
- Redemption Rejection: Hiryu turned down Sougo's advice to live for the present instead of holding onto grudges of the past, considering it an insult.
- Resurrective Immortality: His Another Rider army is granted this thanks to his abilities as the demon king, reversing time on the off chance any of them are killed.
- Right for the Wrong Reasons: Technically, according to Over Quartzer, in the grand scheme of things, Sougo really was indirectly responsible for what happened to him, but he and Oma Zi-O are the wrong versions behind it. Final Stage implies he learned about SOUGO's existence since he had now become Barlckxs.
- The Rival: A more proper one for Sougo/Zi-O.
- Shadow Archetype: As the new demon king, Hiryu shows the worst traits of Sougo and Geiz taken to the extreme, showing Sougo’s potential to become a deluded tyrant who will ruin all lives under his own vision, and Geiz’s hatred of Sougo if he lost sight of his sense of justice and stopped caring about anything else as long as he reached his goal.
- Smug Snake: He's obscenely self-important and self-assured, especially as Another Zi-O II. Ultimately however, he proves to be far less than he thinks of himself and turns out to be barely more than a stepping stone in Swartz's plans as Kaito removes the Zi-O II Anotherwatch from the story entirely at the end of the Another Zi-O II Arc.
- Straw Nihilist: His later appearances show how he believes that fate had originally chosen Sougo to be eventually rewarded while he is still doomed to suffer, claiming that people like himself can only hold on to the past because nothing else awaits them. Sougo ultimately refuses to accept this knowing that time only moves forward, so both of them should as well.
- Then Let Me Be Evil: The way he sees it, he lost his parents because of Sougo apparently becoming Oma Zi-O, causing all the time traveling events to happen, so he'll gladly become the new future tyrannical king if it means getting his revenge on the original. Final Stage has him conclude that being Born in the Wrong Century had something to do with it as well.
- Time Master: Once he becomes Another Zi-O II, he gains the ability to, in his words, "Rewrite time to his heart's content". Making matters worse is that unlike Sougo, Hiryu has complete control of his abilities.
- Took a Level in Badass: In the alternative future created in Episode 41, he becomes Another Zi-O II and takes Sougo's place as Oma Zi-O. Episode 41 shows that he has powers equal to Grand Zi-O and has total mastery of those powers which lets him finally best Sougo. Episode 42 has him simultaneously take on Geiz Revive and Decade.
- Tragic Villain: For all his spite, pettiness, and willingness to cross any line to hurt Sougo, at his core, Hiryu is a broken man who is stuck in a past that he never chose and has been deluded by Swartz into thinking that he could evolve past it all as a king. Even in his worst and most hateful moments as part of the Another Zi-O II arc, all of it is because he is simply too filled with anger and resentment that he honestly can't believe Sougo or anyone would ever be able to comprehend what he has went through and remembered for so long. And at the end of his arc, Swartz tells him to his face that he was merely a pathetic man who thought he could be king. Final Stage seems to cement him as a Straw Nihilist who believes he was cast aside by fate and truly was stuck in the past (along with viewing the Heisei era as a mess), but Sougo rebuffs that time only marches forward, and if he doesn't move forward as well, then he'll always lose to him.
- Underestimating Badassery: He thought nothing of Geiz Revive and was crushed as a result. The only reason he is still a factor at all is because Swartz bailed him out.
- Unwitting Pawn: Despite willingly accepting his Another Rider powers, Hiryu is arguably more of a pawn than the other Another Riders. Hiryu wanted to defeat Sougo because he thought Sougo was the cause of his parents' death. But #27 and #28 reveal that Sougo actually saved his life; Swartz, the man that gave him his powers, killed his parents to create Zi-O.
- Unknown Rival: While Hiryu is dedicated to defeating Sougo, Sougo has no idea who he is.
- Used to Be a Sweet Kid: The flashbacks in episode 27 show that Hiryu used to be a regular kid that was happily looking forward to a trip with his parents but due to the bus accident that Swartz caused, Hiryu grew into a bitter and spiteful young man that would do anything to hurt and kill Sougo.
- Walking Spoiler: His role as the Big Bad of Final Stage is a huge spoiler for the stageshow.
- What Happened to the Mouse?: While Kaito manages to take his AnotherWatch for a later part of the story, Hiryu is not seen again after his final defeat. Swartz doesn't even bother to end his life right there.
- Hiryu eventually returns in Kamen Rider Zi-O Final Stage as Kamen Rider Barlckxs, and eventually Another Ohma Zi-O.
Another Ryuki
Portrayed by: Shun Ishida (live)
Sara's boyfriend, Tatsuya Kano, who originally was her assailant in a car accident. They eventually started dating through his visits in hospital, however after Sara's condition worsened, he was given the power of Another Ryuki by Kamen Rider Odin to start a murder game in the real world, gathering as many lives as he can to save hers. He appears in Rider Time Ryuki.
- Brainwashed and Crazy: Despite having reached the Despair Event Horizon, Kamen Rider Odin forces him to fight by brainwashing him.
- Cool Sword: He wields a larger version of Ryuki's Drag Sword.
- Despair Event Horizon: The moment he learns that Sara is dead from Shinji in Alive A Life, he just gives up.
- Failure Is the Only Option: Sougo and Geiz's cameo in Another Alternative has them say they can't beat him because he has the power of a Mirror World Rider.
- Falling-in-Love Montage: How his developing feelings for Sara are demonstrated. His visits in the hospital start with, in order, a fruit-basket, a giant teddy bear, chocolates and finally a bouquet of flowers.
- Informed Ability: It is stated by Geiz in #1 to have "the powers of a Mirror World Rider"note but never uses them.
- Irony: Since his suit is a repaint of Another Ryuga's, this Ryuki is the knockoff of Ryuga, rather than the other way around. A darker one is the fact this Ryuki is a puppet to Shiro while the original was a Spanner in the Works to him.
- Love Makes You Evil: Tatsuya is harvesting the souls of the innocent to somehow save Sara's life.
- Playing with Fire: Being an Another Rider based on Ryuki, he has fire powers.
- Power Fist: Like the original Ryuki, Another Ryuki has a sinister version of the Drag Visor on his left arm.
- Rescue Romance: An interesting inversion as his relationship with Sara started when he accidently hit her with his car. He visited her everyday in the hospital till his visits became more like dates.
- What Happened to the Mouse?: Following the destruction of his AnotherWatch, his fate is unknown.
Another Blade
Portrayed by: Hikari Kajiwara (live) Hajime Kanzaki (suit)
Hajime Aikawa's best friend, Amane Kurihara, who was turned into Another Blade by White Woz for the express purpose of reuniting Hajime and Kenzaki to re-inititate the unfinished Undead Battle Royale.
- Abhorrent Admirer: What the effects of the Another Blade Anotherwatch turn her into.
- Apocalypse Maiden: White Woz chose her to get Hajime and Kenzaki to meet again so the Undead Battle Royale would finally finish. Episode 30 reveals she also has the ability to absorb Kenzaki and Hajime's Joker powers so she is the only Undead left, finally ending the battle royale with her as the victor and initiating the apocalypse as a result.
- BFS: She wields a large sword that resembles the larger version of the original Blay Rouzer.
- Brainwashed and Crazy: Due to White Woz taking a page from Swartz's book, Amane is forced the Blade Anotherwatch and goes on a rampage under its influence to seek out Hajime, whom she has missed for years.
- Chest Blaster: Another Blade can fire an energy blast from her chest armor.
- Climax Boss: Ends up being the final opponent of the second major arc and marks the point where Sougo, Geiz, and Woz end their bickering and truly become allies, as well as the start of Zi-O's "path to king-hood" by the collection of the last six Ridewatches.
- Deadly Disc: The hilt of the sword is equipped with a buzz saw, replacing where Blade would put the Rouze Cards into.
- Darkhorse Victory: A very twisted example. She defeats both Kenzaki and Hajime before stealing both of their Undead powers for herself, thereby become the winner of the Battle Royale by default.
- Earn Your Happy Ending: Kenzaki, Hajime and Amane finally get their happy ending when Amane steals their Joker powers. When she was defeated, she also sealed Kenzaki and Hajime's powers in their Ridewatches, making them human and allowing the three of them to interact again.
- Energy Weapon: She can fire a light-blue energy blast from her thorax armor, though it doesn't do much as even Zi-O in basic form only seems discomforted by it than in actual pain.
- History Repeats: In Missing Ace, Amane becomes the human sacrifice of a Rider/Undead to become an Eldritch Abomination. In Zi-O she becomes a mixture of both.
- Joke Character: Played for Drama. Compared to nearly every other established Another Rider, Another Blade's fighting ability is shown to be shockingly low. Another Blade is clumsy with her sword and while her long-range laser-beams hurt, they aren't enough to damage an enemy meaningfully. Zi-O's base form kept up on par with her and Gaim Armor was enough to nearly put her down. If not for the arrival of the person she was looking for, as well as Another Riders' innate Resurrective Immortality effect, the battle would've ended before it really started. However, her endangerment caused Kenzaki to transform and reignite the Undead Battle Royale, which was the reason she was turned at all. Then she becomes Lethal in the following episode, as she absorbs Kenzaki and Hajime's Joker powers, turning into the only Joker left and thus capable of destroying the entire world.
- Locked Out of the Loop: In the TV series, Amane was never aware of Hajime and Kenzaki's true natures as Kamen Riders or Undead. After becoming Another Blade she finally learns the truth.
- Magikarp Power: Another Blade isn't the strongest Another Rider, but she has the power to absorb Kenzaki and Hajime's Joker powers and gain an immense power boost in the process. As Kenzaki and Hajime are both the last Undead and Joker Undead this means that doing so initiates the end of the world as Another Blade is the last "Joker Undead" standing.
- More Deadly Than the Male: Despite her sub-par fighting skills, she ends up being one of the most dangerous Another Riders due to her ability to absorb Kenzaki and Hajime's Joker powers thus starting the end of the world as a result.
- Mythology Gag: Instead of red bug eyes which main Riders and their Another Riders had, Another Blade has a pair of human-like eyes. Possibly a reference to Tachibana's final fight with Giraffa Undead wherein his Rider helmet's eye cracked and partially exposed his face, alongside a blood leak. In addition, Another Blade's facial design also resembles Hajime's infamous "I will kill you!" expression from the home series.
- She's All Grown Up: Amane was a pretty kid during the original series, but has now grown up after the events of the series ending.
- Spikes of Villainy: As Another Blade, she is covered in blades from head to toe.
- Sword Beam: She can generate dark energy and channel it as energy slashes for her Another Blay Rouzer or for energy bursts.
- They Call Him "Sword": They call her Another Blade.
- Took a Level in Badass: Episode 30 has her taking Kenzaki and Hajime's Joker powers making her much stronger. Able to easily take on Geiz and Black Woz.
- Top-Heavy Guy: Back in the day, Kamen Rider Blade was the point when the thick upper body armor on Rider suits was reaching egregious levels - Another Blade exaggerates it. The bulk of her upper body actually seems to actively hampering her mobility.
Another AgitΩ
Portrayed by: Various Extras (live) Hajime Kanzaki (suit, main)
A variant of the late Another Agito created by the Time Jacker. From a single unit, they evolved from the G3 Team and officers via infection as part of Swartz's plan to draw Shouichi Tsugami back to Japan to steal his power of Agito.
After stealing Shouichi's power however, Heure uses the Agito Ridewatch produced on the Another AgitΩ leader to prevent it from falling into Zi-O's hands, evolving it into Kamen Rider Agito Ground Form. Under Heure's control, it proceeds to remotely evolve huge hordes of random civilians into more Another AgitΩs, causing widespread panic.
- De-power: Despite becoming Kamen Rider Agito, the leader loses the Ridewatch after being punched by Zi-O, and reverts back to Another AgitΩ, just in time to get hit with a double Trinity Kick.
- Energy Weapon: When infused with the power of Agito Ridewatch, the Another AgitΩ leader gains the ability to turn victims into Another AgitΩ by firing a purple beam from its chest.
- Hammerspace: Another AgitΩ leader can pull weapons that are the equivalent of Agito's Flame Saber, Storm Halberd and Shining Caliber out of his Ankh Point.
- Killed Off for Real: Likely averted. When they're defeated in 2001: Unknown Memories, no civilians are seen falling out of the explosions like with other Another Riders. Behind the scenes however, it is more likely that having every infected civilians fall out of the explosions would've cluttered the shot far too much.
- Mook: Looks to be this for the Another Riders due to their status as a horde, most keeping their civilian clothing intact much like the Masquerade Dopants did.
- No Name Given: Along with Another Double, at least to the leader, but then again, it made sense given what he was supposed to do.
- No Kill Like Over Kill: The Another AgitΩ leader and his army get hit with Agito Trinity Kick and Zi-O Trinity's Trinity Time Break Burst Explosion.
- Scarf of Asskicking: Each one has a pair of scarf protuding from the back like the original Another Agito, as well as The Lords/Unknowns of the original series.
- Spell My Name With An S: Its technical name is simply just Another Agito. However, its chestplate bears the stylized "AgitΩ" instead of a simple O and is referred to as "Another AgitΩ" on this wiki to differentiate it from the original Another Agito from Agito's own series.
- Took a Level in Badass: In episode 32, Heure extracts an AgitΩ Anotherwatch from an infected Another AgitΩ and uses it to steal and imbue it with Shouichi's Agito powers before putting it back into the leader, evolving him into Kamen Rider Agito Ground Form.
- The Virus: Each Another AgitΩ is focused on biting normal people to increase their numbers. Making matters worse, Another AgitΩs will prioritize converting more victims over continuing battle with a Rider.
- Zerg Rush: What makes them so dangerous is while Sougo, Geiz and Black Woz can easily take down a single Another AgitΩ, the Another AgitΩs are more focused on increasing their numbers than fighting them, thus they are able to overwhelm our heroes in pure numbers.
Another Hibiki
Portrayed by: Rihito Noda (live)
Sougo's childhood friend Tsutomu Tsuzumiya, who was also a former disciple of Hibiki under Kyosuke's tutelage until he quit some time prior. He was turned into Another Hibiki by Heure in accordance to his wish of becoming an Oni, as well as bring the actual Hibiki out.
- Alliterative Name: Tsutomu Tsuzumiya
- Anti-Gravity Clothing: Another Hibiki's "shawl" goes around and over the back of his head, and where his armor is, referencing the Kongōrikishi, the wrathful and muscular guardians of the Buddha.
- Brainwashed and Crazy: He seems unable to control his Another Rider powers and as such he is unable to control his transformation and goes on rampages under its influence. After Heure abandons him due to his seeming uselessness in finding the Hibiki Ridewatch, he is more in control of himself but still rampaging, best shown when he responds to Kyosuke's apology with a Big "SHUT UP!"
- Broken Pedestal: It was implied he quit his oni training due to learning his mentor Kyosuke was not the heroic Oni Hibiki he had admired so much. It becomes rebuilt when Kyosuke's Character Development allows him to use the Hibiki Ridewatch and become Hibiki, freeing him from the AnotherWatch.
- Curb-Stomp Battle: Every battle Another Hibiki gets into is one of these for him in episode 33.
- Dual Wielding: His own version of Ongekibou Rekka.
- Earn Your Happy Ending: Thanks to Kyousuke's Character Development, Tsutomu is freed from Another Hibiki and regains his faith in him.
- Joke Character: Another Hibiki is not a very good fighter as he gets thrashed in every battle he gets into. It is only because of Heure's time powers and Kyousuke doing everything in his power to protect Tsutomu that he hanged around for two episodes. The second those protections are gone, Another Hibiki goes down fast.
- Malevolent Masked Men: Worse than most, not only to oppose Hibiki's faceplate that lacks anything that looks like a face, it looks more like Nested Mouths, due to his appearance.
- Mythology Gag: Another Hibiki's name being labelled vertically references how the original series' logo was also vertically oriented with the words read from top to bottom.
- Nested Mouths: If you look close-up on Another Hibiki's face, what seems to be his tongue is another set of lips lined with a grinding expression of teeth, which fits perfectly given his Makamou theme.
- Playing with Fire: Not only can he breathe fire, but he can ignite his Another Ongekibou Rekka, as well as enlarge them for far-reaching attacks.
- Poor Communication Kills: His mere existence creates this, as he is close enough to an Oni in design that he can be easily mistaken for a corrupted one instead of an Another Rider. This leads Kyosuke trying to get Tsutomu to snap out of it through words while protecting him from Zi-O and Geiz, not knowing that while forcefully changed Another Riders can resist their commands slightly, they can't escape the Anotherwatch's power through will alone.
- Screw This, I'm Out of Here!: He tries to escape after Sougo and Geiz change into Zi-O II and Geiz Revive while thrashing him.
- Too Many Mouths: Not only with the above and mixed with Multiple Head Case, but also has a second head that resembles Hibiki's Henshin Onsa, but fiercer. He also has two golden shoulder pads that look like oni heads, complete with horns and fangs. This, in total, brings the numbers of mouths to about five.
- Wild Hair: Just like the Makamou Parents, he has black, wild hair on the back of his "head."
Another Kiva
Portrayed by: Yumiko Shaku (live)
A woman named Yuko Kitajima whom Sougo claims was his first love back when he met her as a high schooler when he was a kid. Sent to prison in 2015 for a murder she claims she did not commit, she was given the power of Another Kiva by Ora in 2019, which allowed her to break out of jail. She targets the lawyers that have wronged her as an act of vengeance, passing "judgement" onto them for her goal of correcting the world's laws as the Queen of the World.
- Affectionate Nickname: "Sailor-san/Miss Sailor" from Sougo, due to him mistaking her for the high school student in a sailor uniform he had a crush on since his childhood.
- Ambiguously Human: She can somehow lift a manhole lid even before becoming Another Kiva,note use it to block blasts from Ginga, and to top it all off, has a sense of smell that would put bloodhounds to shame while making absurdly accurate predictions just from the scents alone.
- Asshole Victim: After it turns out that she is a manipulative monster who did the crime after all, she ends up getting killed by the ever-malicious Ora, who turns spiteful after being mistreated by her.
- Bat Out of Hell: A given since she is based on Kiva.
- Believing Their Own Lies: Yuko honestly believes she was framed for murder, but when Geiz travels to the scene of crime in episode 36, he witnesses her committing the crime in person.
- Breath Weapon: Another Kiva can generate energy constructs that take the form of bats and launch them from her mouth for offensive purposes.
- Carry a Big Stick: A given due to having the Dogga Hammer.
- Cool Sword: A given due to having the Garulu Saber. Though she loses it once Jiro ditches her.
- Do Not Taunt Cthulhu: Her constantly putting down Ora finally catches up with her when Ora kills her after she loses the power of Another Kiva.
- Drunk with Power: The second she gets Another Kiva's powers, she grows an enormous ego believing she is destined to be queen and thus she has the right to do what she wants to right the world's laws. She even gets infuriated when Ora dodges her slap as someone defying her.
- Evil All Along: She was never framed for the murder that got her arrested. Geiz bears witness that she beat a woman over the head with a manhole cover and killed her.
- The First Cut Is the Deepest: Played With. She was implied to be Sougo's first love from when he was a child and he still has a soft spot for her to this day. Ever since she left after playing with him for a day, he had no other romantic interests. However, as Sougo recognized a woman whom he helped fix her bike as his actual first love, it is implied that Yuko lied about it to begin with.
- Foil: Particularly to Sougo, due to her desire to become the 'World's Queen" is parallel to that him wanting to become a king. They both want to become royalty to make the world a better place and set about their goal by the Time Jackers. But Yuko is openly defiant to the Time Jackers even harming Ora while Sougo's been manipulated by Swartz since childhood. And while they're both manipulators, Sougo is open and honest about how he leads people on, at least after the fact, while Yuko is willing to pretend to be someone's first love to get his power at her side.
- Foreshadowing:
- The first scene of 2008 has Woz watching over her already together with her then-lover Tetsuya, implying that she could not have been the girl who had taken an entire day out alone to play with Sougo as a child, and even if she was she never had any feelings for him.
- In the flashback, we hear the girl call Sougo "kawaii no bouya" ("cute boy"), while Yuko calls him "kawaii no ko" ("cute kid"). Sougo is able to recognize his true first love at the end of episode 36 when she calls him by the first nickname.
- Also, there's the fact that if you saw the actual Kiva series, you know a romance ending in any way but as tragically as possible was unlikely. Particularly, there was an arc where Wataru, the true Kiva (a Rider destined to be king) has as his first love with a woman who was a queen of sorts but turned out not to be as innocent as we thought. Don't be surprised when they end up pretty much the same way!
- Giving Someone the Pointer Finger: When she declares her victims as "guilty".
- I Reject Your Reality: While she's most memorable for believing her own story about being falsely locked up, she also said she would pretend that Ginga doesn't exist in 2019: First Love, Finaly!. This is after he blasted her in the face and gave her a Shut Up, Hannibal!, and the Time Jackers and the Riders cooperated to try and get her help. She even untransformed and walked away from him mid-battle.
- Improbable Weapon User: Has a tendency to use manhole covers. This is also how she committed the murder that got her locked up.
- It's All About Me: Seems to be under the impression that the Time Jackers are her underlings and that she received her powers out of destiny and superiority.
- Irony: Yuko decided to ignore Ginga, yet it's Woz using that power that ultimately stops her.
- Killed Off for Real: Tragically, even when Woz GingaFinally managed to stop Another Kiva, she was then killed by Ora while weakened.
- Lady in Red: Her preferred look once she's out of prison (and coincidentally Kiva's own default color).
- Lady of War: She puts quite the effort into mantaining her good looks and can beat people to death while still looking just as good. The first thing she does after breaking out of prison is having her nails, face and hair done. She also gets some new clothes and heels.
- Leg Focus: Whether it's stopping a car or sending manhole covers out of the ground, her legs tend to get Koichi Sakamoto-level focus.
- Literally Shattered Lives: She can kill people by extending her fingernails to impale them, turning them into technicolored stained-glass statues which shatter like Fangires do.
- Love Makes You Crazy: She goes to yandere levels of crazy, plotting murders for Tetsuya's subsequent lovers while believing it was never her fault. This was the reason Tetsuya broke up with her to begin with.
- Madness Mantra: Keeps muttering "guilty" while chasing her ex Tetsuya at his wedding.
- Manipulative Bitch: When Sougo recognizes his true first love at the end of episode 36, it's implied that Yuko was just playing along to manipulate him.
- Miscarriage of Justice: Yuko has been in prison since 2015 due to a murder charge that she says she was framed. Subverted when Geiz went back in time and bore witness to the crime itself.
- More Deadly Than the Male: A more conscious example compared to Another Blade, she quickly proves to be much more dangerous and uncontrollable than the other Another Riders.
- Multiple Head Case: As Another Kiva, she has a red, angry-looking bat head with long ears on top of her head.
- Muscles Are Meaningless: Despite a relatively petite frame, she can use a steel manhole cover to great success as both weapon and a shield, though this may be attributed to being imbued with her Another Kiva powers, as prior to her arrest she was shown to have much difficulty handling a heavy manhole cover to commit her murder.
- My Greatest Failure: She is this to Ora due to being uncontrollable as well as harming her face.
- The Nose Knows: She is naturally gifted with a strong sense of smell that allows her to accurately read her targets' last activities, such as her lover Tetsuya getting a new girlfriend ever since her imprisonment.
- Not-So-Well-Intentioned Extremist: For all the trouble she goes through to right her so-called wrong, her claim for being falsely imprisoned turns out to be a complete lie. Her arrest was for beating a man’s girlfriend to death and she is only doing it all for petty vengeance.
- Red Herring:
- Her belief in being innocent and Sougo's vision of the past in episode 35 implied that Tetsuya was the actual murderer as he was at the crime scene, however episode 36 reveals it was not the case; Yuko was indeed the murderer herself while Tetsuya stood nearby as a shocked witness to the crime.
- She appeared to be fine with Tetsuya moving on with his life and never held any grudge against him for her arrest, blaming the law instead with her agenda seemingly being solely to reform the world's laws as its queen. Episode 36 reveals her true agenda was to murder Testuya's fiance on their wedding day. She was never fine with him moving on from her at all.
- The end of episode 36 reveals that Sougo's childhood crush is not her, but a much nicer lady just like how he remembered her to be.
- Revenge: Her first order of business after being freed is to take revenge on the people that got her locked up.
- Sherlock Scan: Besides scents, she can also identify fabrics, traces of cat hair and injuries and make appropriate conclusions.
- Shout-Out: His appearance is based off Spawn, from his titular series.
- Skewed Priorities: When Kamen Rider Ginga arrived to destroy the world, Another Kiva is more interested in fulfilling her "revenge" than team up against the bigger threat, instead opting to pretend he isn't there.
- Something about a Rose: Has two metallic roses on her chest armor, connected by a chain.
- Summon Magic: When transformed into Another Kiva, she can bring forth the Arms Monsters to fight for her.
- Sure, Let's Go with That: The end of #36 implies she just went along with Sougo’s belief she was his first love out of convenience once he declared her to be so.
- Ungrateful Bitch:
- Among the lawyers to whom she was getting revenge on, including her own attorney, who failed to defend her despite his efforts.
- She has absolutely no gratitude for Ora giving her Another Kiva's power and freeing her, saying it was her destiny of becoming queen that gifted her that power. She even attacks Ora when she tries to rein her in.
- Unwitting Pawn: An inversion. She actually follows the Time Jackers' goals to produce a new ruler unlike most other Another Riders, but she refuses to listen to them, openly calling Ora a "stepping stone".
- Used to Be a Sweet Kid: Sougo's flashbacks showed she was a kind girl who took the time out of her day to cheer up a sad kid she just happened to pass by. This seemingly disappeared after her arrest. Episode 36 reveals, however, that she wasn't the girl who helped Sougo.
- Yandere: Implied to be the reason Tetsuya broke up with her in the first place, and then proven so when it was revealed she murdered his next girlfriend, complete with Laughing Mad after doing the deed. It is to the point where Tetsuya had to move to the outskirts just to protect his current fiance after her arrest, and even so Yuko still manages to find them on their wedding day, ready to kill her with yet another manhole cover on-hand.
- Waif-Fu: She is more intimidating in behavior than looks and yet she uses a steel manhole cover as a weapon and forced a car to stop with her heel.
Another Kabuto
Portrayed by: Hidenori Tokuyama (live) Yasunari Tsukagoshi (suit)
Sou Yaguruma/Kamen Rider KickHopper, an ex-member of ZECT and one of the Hell Brothers, who was granted the power of Another Kabuto supposedly by Heure when the second coming of the Worms occured in 2019 due to distortions in space and time. He protects and works with a Worm copying his old partner Shun Kageyama in his plans to have humanity wiped out with a planet-sized meteor carrying more Worms that is bound to crash into Earth.
- Alas, Poor Villain: Episode 38 really just shows how much Yaguruma misses Kageyama, that he's willing to let Earth be destroyed if he can be with his "brother" again because Earth was already a hell for him. Geiz even feels sorry for him at the end of the episode.Sou: Go ahead and laugh.
- Ax-Crazy: Not much has changed since the end of his series.
- Big Brother Instinct: Yaguruma always shows up to protect Kageyama from danger and calls him his brother, even though it just a Worm mimicking him, and he knows that.
- Combat Pragmatist: After being defeated by Woz GingaWakusei, Another Kabuto fades to reveal he was transformed into KickHopper beneath his Another Rider transformation, allowing him to continue fighting.
- Despair Event Horizon: After the false Kageyama bites it spitefully denying his last request, Yagaruma wanders off in a haze asking to be laughed at for being so pathetic.
- Last Request: Just before the Worm pretending to be Kageyama dies, Yaguruma asks for him to call him brother one more time. The Worm spitefully refuses as he dies in his true form, saying he isn't Kageyama and they aren't brothers.
- Logical Weakness: Woz Ginga decides if he can't tag Another Kabuto, he might as well just bombard the entire area, since Super-Speed is useless when you've got nowhere to run.
- Mythology Gag: Another Kabuto's belt buckle is a yellow larva with red markings curled into a ball, which evokes the design of Kamen Rider Stronger's Electrer belt; Kabuto was specifically designed to be an homage to Stronger.
- Not Brainwashed: At first the characters believe that the Anotherwatch has caused him to mistake a Worm mimicking his old partner Kageyama for the genuine article. Yaguruma knows full well that this Kageyama is a fake, since he was the one who mercy killed the original; he's simply too grief-stricken to care.
- Only Friend: Yaguruma only really cares about Kageyama as he feels Earth is already a hell for him.
- The Only One Allowed to Defeat You: He says to Geiz in episode 38 that part of the reason he's protecting Kageyama is because he feels if Kageyama needed to be killed, he should be the one to do it again. Geiz takes advantage of this by killing Kageyama himself, sending Yaguruma into a blind rage that allows Kagami to swiftly finish him off.
- O.O.C. Is Serious Business: At the end of episode 38 after the Worm that imitated Kageyama died in his original form saying he isn't Kageyama and they weren't brothers. Yaguruma is asking for people to laugh at him as he stumbles away.
- Playing with Fire: His own version of "Rider Kick" can generate fire.
- Shadow Archetype: Part of the reason Yaguruma is protecting Kageyama is because he feels if Kageyama has to be killed then he should be the one to do it, mirroring Geiz's friendship with Sougo. He's essentially Geiz if Geiz ever stops caring about the world as a whole and focused on his own desires.
- Shock and Awe: Along with fire, he can also channel electricity into his "Rider Kick".
- Stealth Pun: Its head bears a bit of a resemblance to a samurai's helmet. In other words, another "kabuto".
- Super-Speed: Like the Zect Riders, Another Kabuto can use Clock Up ability to the same effect as the original.
- Unwitting Pawn: Averted, Yaguruma not only knows that the Kageyama in front of him is just a Worm copying his old partner but also this Kageyama's goal is for a planet sized asteroid filled with Worms to land on Earth so they can take over the planet. Yaguruma just doesn't care.
Another Den-O II
Portrayed by: Dai Goto (live)
- All for Nothing: Even if Takuya did "save" his sister, her illness was terminal and she would have died anyways. As such, he spent the past two years hating Yukihiro, for no reason.
- Be Careful What You Wish For: Not him, but Yukihiro, who gets into a contract with a Mole Imagin with his wish being to "help Takuya". The Imagin does this at first by fighting Another Den-O II with the Riders in an attempt to return him to normal. But when Takuya achieves his objective of hijacking the DenLiner, the Mole Imagin considers Takuya "helped", declaring their contract complete and hopping into the created portal to 2017.
- Bittersweet Ending: Takuya is defeated and is now aware that his sister’s disease is terminal and that she is going to die soon, but has come to terms with the fact that Sayuri is trying to die on her own terms by spending one last moment with her boyfriend Yukihiro at one of their cherished date spots before death and wishes them happiness.
- Climax Boss: Endo is the last opponent faced before Sougo gains access to the GrandZi-O Ridewatch, and afterwards, he is forced to fight Another Zi-O II and then Another Drive and Another Decade.
- Cool Train: A given since he is based off of Den-O, due to hijacking the DenLiner.
- Drunk on the Dark Side: Implied. While Takuya's main goal is to save his sister, he begs for Ora to re-sire him once more after his initial defeat and attacks a group of citizens for no apparent reason shortly after.
- Eyeless Face: His horns replace his own eye sockets.
- Green-Eyed Monster: Takuya is envious of his sister's boyfriend Yukihiro, and blames him for her death. It turns out to be a gross misunderstanding.
- Help Yourself in the Future: The Mole Imagin used the Den-Liner to bring some versions of himself across the timeline as extra muscle.
- Knight Templar Big Brother: Little brother but the same idea due to the corruption of the Anotherwatch, he is dedicated to protecting his older sister even knocking out his past self in episode 40.
- Light Is Not Good: Despite having a white palette, Another Den-O II is a Jerkass who is envious of his sister's boyfriend.
- Macguffin Delivery Service: While Zi-O Trinity was busy dealing with Zeronos Vega form, Another Den-O uses the opening to invade and hijack the DenLiner and, defeating the Taros who were still onboard following the its repair.
- Madness Mantra: When Another Den-O II reaches his sister's room, he keeps saying that if it weren't for Yukihiro taking her out of the hospital, she'd still be alive.
- Me's a Crowd: Not him, but the Mole Imagin that teams up with him uses the stolen DenLiner to draft multiple near past versions of himself in the final fight of episode 40.
- No Kill like Overkill: The Cold Opening was just a preview of the utter Curb Stomp Takuya receives with Grand Zi-O. All Twenty Time Break has him get mauled by Build Genius from when Sento was striking down Owl Lost Smash, Gaim Suika Arms from when Kouta first became the aformentioned form to stop the rampaging Inves and Armored Rider Bravo, OOO GataKiriBa Combo from when Eiji was finishing off the Piranha Yummy horde, and Kuuga Pegasus Form from from when Yusuke sniped Me-Garume-Re/Chameleon Gurongi with the help of Gouram, at the same time.
- The Power of Hate: Yukihiro never told Takuya that Sayuri’s disease was terminal, as Sayuri knew Takuya was suffering enough as it was and might have shut down following her death. Thus, Yukihiro let Takuya blame him for Sayuri’s death as a means of being able to continue on.
- Punny Name: His last name, Endo, is actually an anagram of Den-O.
- Sword Beam: Similar to the Sword Form's Extreme Slash finishers, Another Den-O can summon rail-shaped purple energy slashes, controlled by his daggers.
- Shout-Out: Just like the first, his appearance is based off Oni Momotaro a character from Momotaro Jigoku-hen, a Ken Ishikawa manga.
- Stronger Than They Look: Due to going up against the likes of Zi-OTrinity and Geiz Revive, Another Den-O II seems to be a downgrade from the first... Until he hijacks the DenLiner from the Taros and takes the other three down in a matter of seconds, knocking down Kintaros in one hit.
- Villain Team-Up: Ironically, he teams up with the Mole Imagin who made a contract with Yukihiro, as shown as the Imagin uses the stolen DenLiner to save Another Den-O II and attack Geiz Revive Shippu.
- Well-Intentioned Extremist: He stole the DenLiner so that he can go back in time and save his sister from dying because of Yukihiro. Unfortunately, it turned out to be a misunderstanding and his attempt to save his sister would never have worked anyways.
Endgame Riders (Unmarked Spoilers)
Another Drive
Portrayed by: Ayaka Konno (live)
"Soon you will be gone, and I will replace you. Now isn't that some very good news? I mean, without your power... you serve no real purpose, do you?"
An Another World version of the Paradox Roidmude/Roidmude 108 AKA Dark Drive from an altered variation of the events during Surprise Future, who was summoned by Swartz by using Kazuma Nishimura as a catalyst. Once summoned, it was granted the power of Another Drive by him. It copies Ora's form, targeting Heure for assassination to return the time power Swartz gave him while also aiming to eliminate and replace Ora herself as the true Ora.
- Alternate Self: Of the original Roidmude 108/Paradox Roidmude in his own series. Considering that this 108 won the fight against Drive, this also means that she caused the second Global Freeze, stopping everything dead in its tracks, forever.
- Become a Real Boy: A very dark version as Paradox Roidmude wants to kill human Ora and take her place.
- Big Red Devil: The Type Speed spoiler on her head is jagged and warped to look like horns.
- Canon Character All Along: After a double red herring that plays Another Drive up as two different characters unrelated to Drive, her true identity is revealed as the villain of Surprise Future.
- Cast as a Mask: Before the reveal of her apparent true identity as Ora, Another Drive's voice is a generic monster's. After that, her voice is replaced by Ayaka Konno's.
- Cool Car: Another Drive has the ability to summon an Another Tridoron to help in combat, and can even use it to perform a copy of the real Drive's SpeeDrop Kick.
- Curb-Stomp Battle: Paradox is subjected to a brutal one for mocking a dead Heure in front of Sougo, who responds by going Grand Zi-O, beating up Another Drive who can't even make a single move against him, before summoning Drive to destroy both her Another Tridoron and her in an All Twenty Time Break.
- Early-Bird Cameo: Was seen as a statue when the timeline was altered to have Another Zi-O II be the demon king before she debuts proper in Episode 44.
- Fashionable Asymmetry: Her design is meant to emulate a car wreck with its dented parts formed into a body.
- Humanshifting: Another Drive can transform into a human being of her choosing. This ability is similar to how Roidmudes can assume human forms. This is forshadowing to her true identity as the Paradox Roidmude.
- In Love with Your Carnage: Another Drive spent most of episode 45 mocking Ora as pathetic for losing her powers but is ecstatic when Ora murders Heure to protect herself. She even praises Ora as being worse than her.
- Luckily, My Shield Will Protect Me: On her left arm she has a dented car door covered in police tape; the fact that it can shoot energy blasts makes it a parallel for Drive's Door Gun as well.
- Logical Weakness: Another Drive's Heavy Acceleration relies on the manipulation of gravity to distort time. However, since WozGingaFinaly has even stronger control over gravity, he has no problems nullifying it. And actual Time Stands Still powers can freeze Another Drive, thus immediately canceling her powers out.
- Kill and Replace: Paradox wants to kill Ora and take her place as the real Ora.
- Killed Off for Real: Grand Zi-O's Curb-Stomp Battle against Another Drive is so brutal, not only is the Anotherwatch destroyed, but her vessel and both versions of her cores as well.
- Mythology Gag: Another Drive's head evokes Super Deadheat Drive from the movie Surprise Future by having a half-and-half design, but it is taken a step further by her human-like left eye, which references the specific scene where Dark Drive beats Shinnosuke so badly that the left side of the Drive helmet breaks and exposes his face underneath it. This is foreshadowing, considering that Dark Drive was the Paradox Roidmude.
- Red Herring: It was hinted early on in episode 44 that Another Drive was Kazuma Nishimura, a marathon runner and high school classmate of Sougo, due to him being kidnapped by Swartz and being declared missing according to the news with him possibly face another issue like with Another Hibiki. At the end of the episode, it was shown that Another Drive appears to be Ora. And then episode 45 reveals that it is not Ora but an Another World version of Roidmude 108/Paradox Roidmude.
- Samus Is a Girl: The one behind the mask isn’t some helpless victim. It’s Ora in some unknown goal. Eventually subverted as Ora never became Another Drive in the first place. It was 108/Paradox Roidmude disguised as Ora.
- Shout-Out: Keeping with Kamen Rider Drive's Knight Rider meets Kamen Rider theming, Another Drive is loosely based on the incarnation of K.A.R.R. from the 2008-2009 TV series, which transforms into a robot.
- Speak Ill of the Dead: Another Drive mocks Heure, who was literally just killed by Ora after the latter decided to kill him so she can get his time power. Sougo makes sure that it is the last thing she ever does.
- Stealth Pun: As mentioned above, the actual Drive’s forms are all based around types of cars, while Another Drive is patterned on a car wreck.
- Super-Speed: She also has the true Drive’s speed, with episode 45 revealing she is on par with Geiz Revive Shippu.
- Time Stands Still: Has access to the Roidmudes’ Heavy Acceleration abilities, which the original was said to possess but never actually used. However, like the original Heavy Acceleration, it’s not actual time stop, as people can still barely move and Heure has been shown to stop Drive in its tracks with his actual time-freezing abilities. Justified because Another Drive is a Roidmude.
Another Decade
Portrayed by: Kentaro Kanesaki (live)
- Adaptational Badass: Invoked with the Riders he summons. They're basically versions of the original villain Riders if they had won in their final battles, demonstrated when the four riders summoned easily handle Geiz Revive and Grand Zi-O, and Eternal is able to beat Aqua even in his own element.
- Achilles' Heel: Another Decade's Another World Riders are a perfect counter to Grand Zi-O's main Heisei Rider summoning powers. The Another World Riders by their nature are stronger than the canon Riders summoned by Grand Zi-O. Thus the Another World Riders inevitable defeat them eventually overwhelming Grand Zi-O.
- Big Red Devil: Has Decade’s deep magenta colors with massive horns to resemble a devil.
- Composite Character: Not only is he based on Decade himself but Word of God has stated that he is also partially based on N-Daguva-Zeba, a character from Kuuga.
- Death by Irony: Crosses over with Karmic Death, his death is reminiscent of his favorite tactic to pull in the final arc: distracting him from behind followed by a kick that kills him in one hit.
- Early-Bird Cameo: Another Decade was seen as a statue when the timeline was altered to have Another Zi-O II be the demon king.
- Enemy Summoner: Another Decade can use the original Decade’s dimensional walls to summon alternate versions of riders to fight for him, as seen in Episode 44 when he sics G4, Rey, Dark Ghost and Fuuma on Sougo and Geiz.
- Equivalent Exchange: Episode 45 reveals that Swartz can only create the Another Worlds where Dark Riders won by using someone from the real world as a catalyst.
- Final-Exam Boss: He's essentially all the villains in one the way Decade was all the major Heisei Riders in one. He can summon any of the main villains he pleases, and his design takes cues from past major Rider villains in the Heisei era. Word of God has it that he was based on both Decade in his Violent Emotion form and N-Daguva-Zeba from Kamen Rider Kuuga.
- Final Boss: He is the last opponent faced in the show, as well as the entire Heisei Kamen Rider series.
- Finishing Move: For the first few episodes he seems to prefer an energy-charged roundhouse kick, but in Episode 48 he performs an "Another Dimension Kick", a warped version of Decade's Rider Kick with distorted purple energy cards. And each time it lands, the person who takes the attack dies in one hit.
- Hero Killer: Episode 46 has him killing Ora knowing she was attempting to backstab him, finish off the White Woz he summoned when he was already disappearing, and delivers a fatal blow to Aqua. In Episode 48, he would have killed Geiz had Sougo not summoned him out of there with the Trinity Ridewatch, but does kill the alternate version of Chase when he decides to protect Tsukuyomi. He kills Geiz anyways in the last episode while trying to kill Sougo, before killing Tsukuyomi when she reveals she faked her allegiance to him.
- I Reject Your Reality: The Another World runs on this. Swartz can take a person back to the moment of their deepest regret and create a new personal timeline based on the outcome that they wanted to happen. This is also the basis of how he summons Dark Riders as Another Decade, creating timelines where they managed to beat their series' respective Riders, with the side effect of essentially bringing most of them back to life.
- Lotus-Eater Machine: Swartz's Another Worlds function like this, trapping the person inside a "Groundhog Day" Loop fixated on the one moment in time they wished they could redo but succeeding in where they failed, and resetting if something is trying to break the illusion to the prisoner.
- Mythology Gag: The bars on his horns and head resemble a twisted version of Decade’s emblem, with his head in the middle and six bars on each side of the head.
- The overall design of Another Decade recalls Decade's Crossover with Samurai Sentai Shinkenger, where an Ayakashi managed to steal Kaito's Diendriver and transform into a distorted, monstrous version of Kamen Rider Diend.
- No, I Am Behind You: One of his favorite tactics is to let his opponent use their finisher, transport them into a dimensional wall into another wall behind him, and then finish them while their back is turned in their confusion. While he could easily just tank the attack and kill them with no effort, he likely does so to toy with them and make it clear they never stood a chance.
- One-Hit Kill: Possesses his own versions of Decade's finishing moves in the forms of a roundhouse kick, a distorted form of the Dimensional Kick, or a sphere of distorted energy, each killing whoever takes the hit. The only forms that don't die immediately are Grand Zi-O (who still gets detransformed) and Ohma Zi-O.
- One-Winged Angel: Serves as one for Swartz.
- Person of Mass Destruction: Swartz makes it clear of the sheer power he possesses as the Destroyer of Worlds, causing massive explosions with just a wave of his hand.
- Pocket Dimension: Another Decade's most potent ability is his access to the Another Worlds, a series of realities born from regrets and lost possibilities that he can control to his whims or use to summon alternate Riders.
- Satanic Archetype: His demonic appearance makes it obvious enough, while Swartz himself fits other aspects of the bill as the leader of the villains seeking to rule the world, bargaining people with Another Rider powers for his own desires, and a manipulator who’s been leading Sougo down the path of destruction since childhood. There's also the fact that the Rider he stole the powers has been branded as the Devil many times over in his home series.
- Superpowered Evil Side: Swartz is evil already, but his abilities as Another Decade bring to mind Tsukasa's brief time in his Violent Emotion form. The same form, mind you, that destroyed every Rider up to W.
- Thinking Up Portals: Weaponizes the original Decade's dimensional walls in combat, using them to transport enemies, Teleport Spam, or redirect attacks coming towards him.
- Token Good Teammate: In a huge twist of Irony, Swartz's actions in Zi-O vs. Decade lead to Another Decade becoming the only Another Rider to ever be used for good.
- Walking Spoiler: It is impossible to talk about Another Decade's nature without spoiling a lot of things. The fact he exists at all can be considered a spoiler, given Decade is a major character in the story.
- What If?: Another Decade weaponizes this. He can put people into pocket dimensions where they live out happier versions of events that went bad (like Sougo's friend winning a Tekken tournament that he lost in real life), and in exchange he can summon up Dark Riders (and later non-rider Big Bads) from alternate universes where The Bad Guy Won as loyal minions.
- Kamen Rider Dark Drive: Roidmude 108/Paradox Roidmuide wins the fight against Drive, allowing them to cause the second Global Freeze, stopping everything dead in its tracks, forever.
- Kamen Rider G4: Shiro Mizuki defeats Agito, G3, and Gills, allowing Project G4 to continue exploiting Mana and anyone with psychic potential they come across.

Another Zi-O II
Portrayed by: Kimito Totani (live)
See the entry for Daiki Kaito/Kamen Rider Diend on the Past Riders page.Post-series Riders
Another Zero-One (Unmarked Spoilers)
Portrayed by: Soko Wada (live)
- Blow You Away: Another Zero-One's wings can swat enemies aside and launch waves.
- Corrupt Corporate Executive: Staging a robot uprising definitely makes him this.
- Family Theme Naming: Follows the name scheme of the other assistant HumaGear; Izu (Is), Wazu (Was), and himself, Will.
- Fantastic Racism: Dedicated to wiping out humanity on a personal and spiteful level, as shown by his page quote.
- Foreshadowing: The presence of silver in his wings and shoulder armor as well as his Pest Controller ability hints at the later form of MetalCluster Hopper long before Aruto receives it in the show.
- Klingon Promotion: Murdered his boss to become Hiden’s CEO.
- Logical Weakness: Due to its Magikarp Power preventing it from fully impacting Zero-One's Rider Systems, it has no defense against them either. It takes Vulcan and Valkyrie all of one minute to scrap it in a real fight.
- Magikarp Power: The Zero-One Anotherwatch is actually very weak in terms of its ability to wreak havoc on the timeline by itself, as it is unable to erase Aruto's history or even the Zero-One Driver. It instead relies on Will's competence and experiences in the ensuing 12 years to make an impact on history, but it's still far worse than the erasure of even all 19 Heisei Riders combined in the main series.
- This also reflects its downfall: Because its existence didn't hamper the creation of the Shot Risers, it couldn't really defend itself against Vulcan and Valkyrie; who destroy it with relative ease.
- Mistreatment-Induced Betrayal: Played with. Will served under a Benevolent Boss but had Humagear interests in mind long before his siring. Said boss dodging a question concerning how HumaGears benefited working with Humans was presumably the straw that broke the camel's back.
- Not Brainwashed: As part of the running Awful Truth that makes up part of the movie's conflict, Will was never corrupted by the Zero-One Anotherwatch, and had always planned to rebel with the help of the Ark. It's just that the watch gave him the physical strength to execute that plan in time and take over humanity.
- Pest Controller: Another Zero-One can launch out the locust constructs used by Metal Cluster Hopper.
- Powers Do the Fighting: Another Zero-One has a number of monster powers that can sweep away the rank-and-file, but it has no actual fighting ability of its own. Without its side-abilities and mechanical army, it's an absolute joke.
- Red Eyes, Take Warning: Sports blood red eyes right before transforming into Another Zero-One for the last time.
- Remember the New Guy?: Zero-One has barely made any indication he existed before the movie in which he debuted, though it's likely he was decommissioned in the 12 years between Daybreak and Project: Magia.
- The Starscream: Murders Korenosuke Hiden to become CEO of his company.
- Walking Spoiler: It’s difficult to discuss Will without revealing any of the plot of Reiwa: The First Generation.
- What Measure Is a Non-Human?: Discussed. During a meeting with Jun and Sanzo in 2007, Will confronts Korenosuke about whether the Humagears will also be happy working with humans. Korenosuke is unable to properly answer the question.
Another 1
The Another Rider form based off the original Showa Rider that started it all, Kamen Rider 1, used by Finis in Kamen Rider: Reiwa The First Generation, after absorbing Sougo's powers. Things take a turn for the worse when they fuse with Geiz's Time Mazine, becoming Another New 1.
- Attack of the 50-Foot Whatever: Easily towers over the other riders, and seems to rival even Another Kuuga in size.
- Cool Bike: With the twist of the bike making up its entire lower half. After becoming New, it evolves into a grasshopper form.
- Foil: To Another Kuuga from Heisei Generations FOREVER. Both are gigantic Another Rider of the first Rider of an era who are rendered using CGI, transformed from a Time Jacker (Tid as Another Kuuga and Finis as Another 1 respectively), and have another form (Another Ultimate Kuuga and Another New 1 respectively.)
- Mythology Gag:
- The design greatly resembles Kamen Rider Core in its Bike State.
- The cross on its torso is a nod to "Cross Fire", a concept that would evolve into Kamen Rider, and the white, bony skin of Another New 1 recalls Skull Man.
- Also, in Wizard, the Cross of Fire was (in addition to being another nod to the proto-Rider concept) something that represented the heroes' connection to their enemies, the fact that Rider power and villain power is often the same power. This makes it an especially fitting motif for someone who believes that Riders are an instrument of evil and the ones trying to make them heroes are really the ones who've 'distorted history.'
- Another New 1 also has an arachnid motif with its many red limbs, which references the first Kamen Rider kaijin, Spider Man.
- Scarf Of Ass Kicking: Has one that looks like a pair of locus wings. As Another New 1, they become red and more pronounced.
- Secret Identity Vocal Shift: When transformed, Finis switches to a deeper voice, provided by Kouji Ishii.
Another Diend (Spoilers)
- Ain't Too Proud to Beg: After being defeated by Geiz Majesty, the last words out of White Woz's mouth are a simple plea to stop before Black Woz consumes his body.
- Cruel and Unusual Death: Turned to green energy and absorbed by Black Woz.
- Death by Irony: He ate his Anotherwatch when he transformed into Another Diend, only to be Eaten Alive by Black Woz when he is finally defeated.
- Eaten Alive: Black Woz makes sure he stays down by disintegrating and then consuming his body after Geiz Majesty destroys the Diend Anotherwatch.
- Enemy Summoner: Just like Diend, he can summon any monsters as loyal minions.
- Evil Counterpart: Funnily enough, he's this to the previous two White Wozes. Unlike them he never has anything resembling a Heel–Face Turn and doesn't repent at all.
- Foil: The Another Diend form is this to Another Decade, as he pulls the same plan Swartz did, only that he's wants to be the Savior while Swartz sought to become "king".
- Power Parasite: Has the same power stealing abilities as Swartz, attempting to absorb Geiz’s before Daiki interrupts him.
- Not-So-Well-Intentioned Extremist: He claims he’s stealing Geiz’s power so that he can become the Savior and ensure his future. His intention after that is to rule the world.
- Walking Spoiler: The reveal that White Woz is Another Diend and the one who kickstarted the plot of Geiz, Majesty is definitely this.
Another Geiz and Tsukuyomi (novel spoilers)
In the Kamen Rider Zi-O novel, Woz and Sougo are forced to escape into the past after a third alternate Woz from a new timeline dubbed the Third History alters the current timeline, where they are soon attacked by these facsimiles of their friends.
- Satellite Character: While Another Tsukuyomi steals several items from Woz and Sougo useful for unassisted Time Travel, particularly the Decade Ridewatch, Another Geiz only exists in relation to her and Another Woz. It's even explicitly stated that the only reason he's around is because Another Woz has a Stable Time Loop to maintain.
- Stable Time Loop: Another Geiz attacks Woz and Sougo in the altered 2018, prompting them to go to 2068 to dispose of him for real. Upon arrival, Another Woz creates Another Geiz, then sends him back to 2018 to attack the duo, so that they can be prompted to come to 2068.
- Swapped Roles: These versions of the duo swap power-sets: Geiz is Another Tsukuyomi while Tsukuyomi is Another Geiz.
Another Woz (unmarked novel spoilers)
The Big Bad of the Kamen Rider Zi-O novel, this new incarnation of Woz rules over 2068 with the Sougo from the Mirror World, whom he calls "Inner Sougo." To this end, he makes himself Another Woz and vies for the powers of the real Kamen Rider Woz.
- Big Bad: Of the novel, with his timeline's Ohma Zi-O merely being a Puppet King.
- Composite Character: The worst traits of Black, White, and Red Woz rolled up into one insane prophet drunk on power, with some of Swartz's machinations sprinkled in for good measure.
- Stable Time Loop: Enforces two during the plot:
- The first loop he creates is a basic one; he sends Another Geiz and Tsukuyomi to the past to attack the real Sougo and Woz so that they may come to 2068 to deal with him... at which point, the resulting interference prompts him to create Another Geiz and Tsukuyomi; rinse and repeat. Another Geiz is merely added muscle to further provoke the duo, while Another Tsukuyomi loiters around to steal the Beyondriver and Decade Ridewatch, leading to the next loop he plans to enact below.
- His ultimate goal is to use the items Another Tsukuyomi stole to Time Travel and form a time loop where his intervention takes away Sougo's friends and causes him to become Ohma Zi-O without their guidance. At this point, the other loop he had created and the Woz Anotherwatch he builds himself prompts him and Ohma to travel to the past to ensure the latter's ascent just like in the original series, creating the same kind of cycle that Swartz had envisioned.
Other Riders
King
In a non-canon stage show, a man only known as "King" leads the Remodeled Martial Arts Group Z in The '90s. Now seeking to Take Over the World, a new Time Jacker named Spade, who wishes to create an Another Rider based on his own ideas, gives him a unique Ridewatch to become an Another Rider not derived from any other Kamen Rider in history, a fact that seemingly renders him invincible due to it being impossible to create the corresponding Ridewatch.
Now a monster with his powers contained within a Rider device, King captures a man named Kengiro, who he plans to "remodel" to suit the Remodeled Martial Arts Group Z's plans. Meanwhile, Rin Amamiya puts up a one-man resistance against King's schemes, in a world where Riders are merely an Urban Legend.
- Foreshadowing: Though the story King appears in is non-canon, the idea of civilian memories and ideals of the Kamen Riders, especially those that don't exactly exist one way or another, being used to defeat a villain would turn out to have a much more prominent focus in Over-Quartzer.
- Hoist by His Own Petard: Destroyed by his own Ridewatch's powers, charged with the memories of civilians who chose to believe in the Urban Legend of Kamen Riders.
- Logical Weakness: Since Another Rider is not based on any Heisei or Showa Rider in existence, this makes the creation of a proper Ridewatch to defeat him impossible. However, if the watch that powers his form is stolen and charged, it can be used to defeat him.
- Original Generation: King's Another Rider form weaponizes this by preventing Sougo from properly obtaining a Ridewatch to defeat him. However, this is also his greatest weakness, as Rin is able to steal King's watch and give it to Sougo.
- Urban Legend: Likely playing off the lack of any Kamen Rider TV productions in The '90s, King's power is largely derived from the fact that Riders were only seen as this in the time period. This also happens to be a double-edged sword, as Rin is able to steal King's watch and charge it up from supporters of the legends to allow Sougo to defeat him.
No Rider
- Foreshadowing: His presence at first just seems to be a Shout-Out to Norider. Then Over-Quartzer has the actual Rider himself appear.
- More Teeth than the Osmond Family: Has a distinct, very toothy grin.
- Shallow Parody: Seems to invoke this in-universe as his main motif, being a malicious, possibly mindless spoof of Kamen Norider, a legitimate Affectionate Parody series.
